High Quality Content by WIKIPEDIA articles YAG (Yard Auxiliary, General) training vessels are wooden boats built between 1954 and 1958, and based at CFB Esquimalt in Esquimalt, British Columbia, Canada. The vessels are used for training Canadian Forces regular naval officers, naval reservists, and members of the Royal Canadian Sea Cadets in basic seamanship, vessel handling, and navigation. According to the Department of National Defence, in 2000, a total of 1830 personnel were deployed on the YAGs for a total of 585 days and steamed over 25,000 nautical miles (46,000 km) in support of training. YAGs displace 70 tonnes, and are divided into five major belowdecks compartments: right forward, a chain locker, then the forward cabin, containing the galley, one of the heads (washrooms) and the officers eating and sleeping areas, as well as the gyroscopic (gyro) compass.

Laser bonding is a marking technique that uses lasers and other forms of radiant energy to bond an additive marking substance to a wide range of substrates. Invented in 1997, this patent protected technology delivers permanent marks on metals, glass and ceramic parts for a diverse range of industrial and manual applications, ranging from aerospace to the awards engraving industries. It differs from the more widely known techniques of laser engraving and laser ablation in that it is an additive process, adding material to the substrate to form the marking instead of removing it as in those techniques. For metals, parts can be permanently marked with high contrast, high resolution marks for logos, barcoding, identification and serialization purposes, without damage to the substrate. With glass and ceramics, complex surfaces can be decorated or marked and the traditional firing process replaced by a laser, with its permanent bond fired on in seconds. Laser bonding has been achieved by Nd:YAG, CO2 laser, Fiber laser and Diodepumped solidstate laser and can be made by other forms of radiant energy. Laser bonding is often referred to as CerMark, CerMarked, or CerMarking Author: Miller, Frederic P./ Vandome, Agnes F./ McBrewster, John Binding Type: Paperback Number of Pages: 92 Publication Date: 2010/04/23 Language: English Dimensions: 9.02 x 5.98 x 0.22 inches

Okay, just about everyone has a red laser pointer. Heck, we even sell a fine one here at ThinkGeek. But, we're pretty sure you want to be a superior geek - and doing it with a green laser is the way to go. This pointer is significantly brighter (about 50 times) than a red laser pointer and because of its unusual color it is much more noticeable. I mean come on, a 532 nm green laser wavelength is obviously superior to a laughable 650 nm red laser wavelength. And unlike a red laser, the green beam itself can be seen in mid-air in dark conditions, not just the laser beam dot. This allows the green laser pointer to be used for pointing to star constellations (skypointing) and also just generally look cool as hell. The green laser beam dot can be seen at much greater distances than with a red laser pointer. Since green direct injection laser diodes aren't readily available, this pointer is based on the use of Diode Pumped Solid State Frequency Doubled (DPSSFD) laser technology. A high power IR laser diode at 808 nm pumps a tiny block of Nd:YVO4 generating light at 1,064 nm which feeds a KTP intracavity frequency doubler crystal to produce the green beam at 532 nm. Features of this unit include: Very bright green laser at 532 nm wavelength Output power of Range of approximately 9,000 ft (2600 m) in darkness 1.1 mm beam diameter at source Momentary push button switch Solid, heavy duty construction Constant wave output (as opposed to pulse output) Takes 2 "AAA" batteries (not included) Can be used for skypointing, projection on low clouds, signaling, highlighting potential explosives Dimensions: 5.6" x .5" dia 90-day warranty Available in Black or Silver color Interested in quantity discounts or custom logo imprinting?

We report laser desorption from a Room Temperature Ionic Liquid (RTIL) as a novel source for time of flight mass spectrometry. We use the 2nd harmonic of an Nd: YAG laser to deposit intensities of 150 MW/cm2 via backside illumination onto our RTIL desorption sample. A microstructured metal grid situated on top of a glass microscope slide coated with RTIL serves as our desorption sample. The RTIL we use, 1Butyl, 3Methylimidazolium Hexafluorophosphate, remains liquid at pressures below 108 torr. The use of liquid desorption sample allows for improved surface conditions, homogeneity and sample life as compared to Matrix Assisted Laser Desorption Ionization (MALDI) techniques. Our desorption technique is also unique as it allows the study of both multiphoton and acoustic desorption processes within the same time of flight spectra. Our technique yields intrinsically high resolution, low noise data. We observe differences between ion species in their preference for desorption by a particular desorption method. Specifically, we observe desorption solely by acoustic means of an entire RTIL molecule adducted with an RTIL cation. Finally, we report the applicability of this technique for the desorption of biomolecules Author: Harris, Peter Ronald Binding Type: Paperback Number of Pages: 112 Publication Date: 2011/09/11 Language: English Dimensions: 9.69 x 7.44 x 0.23 inches

In the thirty years since the invention of the CO2 gas laser, the major design issue has shifted from how to obtain the desired power level to how to achieve reliable operation. At the same time, the opening of many laser development facilities in the Former Soviet Union has allowed their achievements and design approaches to be understood and appreciated for the first time. Further, the industrial laser user community has identified a number of emerging applications at higher power levels (1520 kW) than are attainable by most commercial devices. In High Power Lasers Science and Engineering, the designers, developers and users of highpower gas laser systems discuss design approaches, methods of enhancing performance, new applications, and user requirements.

Is it possible to use high-powered lasers to project video games onto the bottoms of clouds?
Not really. There are several technical issues that would make the whole thing not worth while.
1. Dispersion. Lasers, like all light, diverge as they move away from the source. You can put a lens in front of the beam to reduce this, but at the altitude of clouds -- which is several thousand feet, typically -- this becomes a huge issue.
2. Image. Video games are, well, video. That means three colors in each pixel, each color balanced to typically 1 part in 256. No laser light show out there works this way. The laser light shows in stadiums can have three colors, and the mirrors do a great job of bouncing the beam around to make pretty shapes. But they don't scan a whole rectangle of pixels, and they don't modulate the intensity of the beam. You need something like a video projector to do that. The good news is, there are video projectors on the market. The bad news is below ...
3. Focus & shadowing. Clouds are not projection screens, and are not flat. So if you dump the laser idea bought a video projector instead, and projected the image upward, you would find that parts of the image would be shadowed by parts of clouds in the foreground. Also, since parts of the clouds are at different distances from the projection lens, parts of the image would inevitably be out of focus, and you couldn't correct that unless you put other parts of the image out of focus.
4. Image brightness. Clouds are, like I said, several thousand feet high. That means that your actual projected image would be several thousand feet across. It takes a HUGE amount of light to illuminate an area that size. (Think football field at night, and multiply by ten.) Good news: there are projectors on the market that just might actually work to do this, at the limit of visibility, if the clouds are particularly low. Bad news: such large projectors cost over $100,000.
In spite of all this, some people have used video projectors to make ultra-huge game-playing screens across a whole wall, for example, when the wall is flat and painted white. It's pretty cool, but you MUST pay attention to the light output of your projector, and size it correctly to the size of your screen. Otherwise the image will be too dim to view.
