Laser-diode-pumped Nd:YAG active-mirror laser
Applied Optics, 1997We describe a simple design, laser-diode-pumped cw Nd:YAG active-mirror laser and present a thermal analysis of the crystal. A cw output power of 2.4 W and an M(2) beam quality value of less than 1.9 at an incident pumping power of 8.9 W were obtained.

The Nd:YAG laser, with its 1,064-nm wavelength, is a mainstay for treatment of vascular lesions. What it may sacrifice in absorption by hemoglobin, it makes up for in depth of penetration. The long-pulsed Nd:YAG laser has been the ideal choice for lesions off the face and for thick or deep vascular targets, although newer short-pulsed high-energy (650 ...

Laser evoked potentials using the Nd:YAG laser
Muscle & Nerve, 2001AbstractPain‐related cortical potentials were evoked by skin stimulation of the face and the limbs with 5‐ns–duration laser pulses delivered by a Q‐switched Nd:YAG laser. Such laser pulses, in the nanosecond range, were able to induce pinprick pain sensations and to evoke reproducible laser evoked potentials (LEPs) without visible skin lesions for an ...

Negative-branch unstable resonator Nd:YAG laser
Applied Optics, 1975The results of an experimental investigation of the performance characteristics of a Q-switched Nd:YAG laser utilizing a negative-branch unstable resonator is presented. Measurements indicate that near diffraction-limited beam quality has been attained with a system in the rangefinder/designator energy category.

[Nd:YAG laser trabeculoplasty].
Ceskoslovenska oftalmologie, 1994The results of ALT and Nd: YAG LTP are presented and compared in group 19 patients. The average IOP reduction and increase of outflow facilities were significant in both methods. Any difference of results between comparing methods were not statistically significant.

Submental Nd:Yag laser-assisted liposuction
Lasers in Surgery and Medicine, 2006Liposuction of the neck is currently one of the most common cosmetic surgical procedures. In the present study, the author describes his experience with neck and jowl laser-assisted liposuction.In this procedure, submental lipodystrophy is treated with an Nd:YAG laser, at a 1,064 nm wavelength.

In this paper, the Nd: YAG laser is designed and stimulated. We considered four levels for the Nd: YAG and analyzed rate equation. With regard population inversion levels we can estimate the gain that is restricted with losses.

Journal of Optical Technology, 2009
A compact pulsed Nd:YAG laser with lamp pumping has been developed that generates trains of pulses at wavelengths of 1.064 and 0.532μm. The optical layout of the cavity and the parameters of the gradient output mirror have been optimized to achieve quasi-uniform transverse distribution of the output radiation.

Ultrastable laser-diode-pumped Nd:YAG lasers
OSA Annual Meeting, 1993We report the performance of the frequency stabilized LD pumped Nd:YAG lasers. We have obtained the frequency noise level of about 3×10−4 Hz/Hz in the error signal and the beat-note line-width of about 100 Hz between two stabilized lasers.

ICALEO '97: Proceedings of the Laser Materials Processing Conference, 1997
A finite element model of the pulsed laser welding process has been developed. This model has been used to calculate the temperature at any point in the material being welded as a function of time. Consequently it may be used to predict the size and shape of weld zones, as well as estimate the cooling rates of the material.
