Green Laser Pointer II $69.99 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? More info here. Warning: Green lasers are very powerful. Pointing at aircraft may land you in jail. Without a Monopoly card to get you back out. Use it wisely. |

Blue Violet Laser Pointer $89.99 A new laser color has just landed at ThinkGeek and we like what we see. Red and even green lasers are now fairly common but blue lasers not so much. So, if you want to have the latest fashionably cool laser color this year, we've got you covered. This laser outputs light in the 405 nanometer wavelength which produces a very unique blue-violet color beam, that is unusual for a handheld pointer. This is also the same wavelength used in Blu-ray DVD players. The shorter wavelength allows more data to be stored than on a standard DVD which uses a red laser (650 nanometer). This laser is certainly awesome but it's also useful for applications such as biomedical instrumentation, imaging, spectroscopy, laser induced fluorescence sensing, microscopy. And if you're not into any of those activities, then this laser can be used to write on photoluminescent material like our Glow Graffiti. |

Transmission hologram viewed in red and green laser light
what formulas do I use for these questions?
can u show steps or a formula for how to solve these problems
1)Light falls on a pair of slits 14.5 µm apart and 74.0 cm from the screen. The first-order bright line is 1.90 cm from the central bright line. What is the wavelength of the light?
2)Monochromatic light passes through a single slit with a width of 0.010 cm and falls on a screen 118 cm away. If the distance from the center of the pattern to the first band is 0.62 cm, what is the wavelength of the light?
3)You have a laser that emits a red light, a laser that emits a green light, and a laser that emits a blue light. Which laser produces photons with the highest energy?
1)
Displacement y = (Order m x Wavelength x Distance D)/(slit width a)
The small angle approximation is
y = mLD/a
2)
Displacement y = (Order m x Wavelength x Distance D)/(slit width a)
The small angle approximation is
y = mLD/a
3)
E=hf=hc/L
