Medical High Power Ho:YAG Laser Design
2012 Symposium on Photonics and Optoelectronics, 2012Ho:YAG laser is widely used in medical area. Double laser rods system can effectively improve the Ho:YAG laser output power. Holmium laser cavity length and the transmittance of the laser resonator mirrors make great influence on the output power . In the particle, simulate the design of the laser.

Intraocular applications of the Ho:YAG laser
SPIE Proceedings, 1995Despite advances in mechanical vitrectomy, cutting dense membranes and fibrovascular strands remains a technical challenge. Widespread acceptance of carbon dioxide and Er:YAG lasers, which cutting potential and coagulative properties were highly evaluated by experimentators, now is limited because of insufficiently convenient fiberoptic delivery ...

Intracavity-pumped 209-μm Ho:YAG laser
Optics Letters, 1992The 2.09-microm Ho:YAG (5)I(7) ? (5)I(8) laser transition is intracavity pumped by a Tm:YAG laser. Separate Tm:YAG and Ho:YAG crystals share a single laser cavity, the Tm:YAG crystal is pumped at 785 nm, and the resulting 2.01-microm Tm(3+) laser emission pumps the Ho:YAG crystal.

Applied Optics, 1993
The adjacent thermal and mechanical tissue damage after normal-mode Ho:YAG (pulse length = 250 mus, lambda = 2.09 mum), Q-switched Ho:YAG (pulse length = 200 ns, lambda= 2.09 mum), and excimer (pulse length = 120 ns, lambda = 308 nm) pulsed laser irradiation of human thoracic aorta samples was studied in vitro.

An Ho:YAG Laser with Double-Pass Pumping and the ZnGeP2 OPO Pumped by the Ho:YAG Laser
Journal of Russian Laser Research, 2013We report an efficient Ho:YAG laser end pumped by Tm:YLF lasers with double-pass pumping. We achieve the maximum continuous wave (CW) output power of 46.0 W with a single-pass pumping and 50.2 W with a double-pass pumping, corresponding to a slope efficiency of 58.0% and 62.8%, respectively.

The Ho:YAG Laser in Shoulder Surgery
2001The holmium:YAG laser emits light at a wavelength of 2.1 μm and can be transmitted through conventional optical fibers. The Ho:YAG laser has the ability to precisely and rapidly resect, cut, coagulate, vaporize and ablate cartilaginous tissues. It causes a minimal amount of thermal necrosis while providing superior hemostatic control [27, 30 ].
