Yag Wavelengths

How Many Photons Does the Laser Deliver?

A laser peripheral iridotomy is a procedure for treating an eye condition known as narrow-angle glaucoma, in which pressure buildup in the eye can lead to loss of vision. A neodymium YAG laser (wavelength = 1064 nm) is used in the procedure to punch a tiny hole in the peripheral iris, thereby relieving the pressure buildup. In one application the laser delivers 4.1 x 10-3 J of energy to the iris in creating the hole. How many photons does the laser deliver?

energy of a single photon is hf, f is frequency and h is plancks constant
net energy = 4.1 * 10^-4
let no. of photons be n
then
4.1 * 10^-3 = nhf = n * 6.626 * 10^-34 * 3*10^8/(1064*10^-9)
n = 4.1 * 10^-3/( 6.626 * 10^-34 * 3*10^8/(1064*10^-9)) ~ 2.2 * 10^16 photons

Yag Training Vessels $68.51 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.

Hubbard Scientific 2380 Fluorescent Minerals Short Wave Collection $48.1 A 15 piece collection of colorful minerals. When light strikes the surface of a mineral some wavelengths will be absorbed and some will be reflected. The color we see results from the combination of reflected wavelengths of light.

MultiSpectral Image $71.7 A Multispectral image is one that captures image data at specific wavelengths across the electromagnetic spectrum. The wavelengths may be separated by filters or by the use of instruments that are sensitive to particular wavelengths, including light from frequencies beyond the visible light range, such as infrared. Multispectral imaging can allow extraction of additional information that the human eye fails to capture with its receptors for red, green and blue. It was originally developed for spacebased imaging.

Improve saggy wrinkled skin with non-surgical wrinkle reduction

Achieve rejuvenated and tighter skin with revolutionary laser technology known as the GentleYAG . Patients see immediate improvements in skin laxity and reduced fine lines without the expense and downtime of surgery.

1. The main cause of wrinkles are stress, prolonged exposure to UV (ultraviolet radiation) and the aging process. The skin’s dermis progressively thins and the network of collagen  loosens and sags. The skin no longer springs back to its original position but rather forms furrows and lines.

The revolutionary laser wrinkle reduction technology employs light energy to effectively remodel the body’s collagen and regenerate damaged skin cells. Whilst other technologies have been developed to stimulate collagen production, the GentleYAG is the most effective.

The Department of Medicine in The University of Hong Kong recently conducted a study on twenty seven patients to assess the effectiveness of Laser wrinkle reduction. The GentleYAG was used to target both the forehead and cheeks on patients with wrinkles. Patients underwent six treatments over six months and were assessed individually before and after the study.  The response was very positive with 70% of patients noticing results after the first treatment.

The wrinkle reduction treatment can take between 15- 40 minutes, depending on the surface area being targeted. Protective eyewear is worn to guard the eyes from the laser light and a numbing cream can be applied 1 hour prior to the treatment for added comfort. The single wavelength light of the GentleYAG technology penetrates the skin until it reaches optimum temperature.

Since the inauguration of Results Laser Clinic in 2004, Results staff have ensured that clients receive the best hair removal experience by striving to be the most competitive, lowest-priced laser clinic in Sydney. Over 40,000 treatments have been performed during the course of company’s operation, with procedures constantly being improved by new technologies and research.
