Triggering Passively Q-switched Microlasers
Advanced Solid-State Photonics (TOPS), 2005We demonstrate triggered operation of a passively Q-switched microlaser at 266nm. For repetition rates between 10Hz and 1kHz, the output performances (mainly pulse energy and build-up time) exhibit remarkably small variations.

Q-switched Ti:Er:LiNbO3 waveguide laser
Optical and Quantum Electronics, 1999Q-switched operation of a Ti:Er:LiNbO3 waveguide laser has been achieved with up to 2.4 W pulse peak power (0.18μJ) at 2kHz repetition frequency with an intracavity Mach–Zehnder-type amplitude modulator. A theoretical model has been developed to describe the laser operation.

Q-Switched Laser Goniopuncture
Archives of Ophthalmology, 1974A new approach to treatment of glaucoma has been tried, in which Q-switched laser bursts are delivered to the anterior chamber angle. Nonthermal effects emerge as an important factor in the biological action of such laser impulses. Laser-induced defects in the filtering zone produced by Q-switched impulses have been traced histologically.

Passively Q-switched Tm:YLF laser
Optics Letters, 2012Stable passive Q-switching of a Tm: LiYF4 laser is obtained using polycrystalline Cr2+: ZnS as a saturable absorber. The achieved maximum pulse energy of 0.9 mJ and peak power of 65 kW for a pulse duration of ∼14 ns represent substantial improvement and highest values for a passively Q-switched diode-pumped Tm laser operating at ∼1.9 μm.

Q-switched unidirectional ring lasers
IEEE Journal of Quantum Electronics, 1969Traveling-wave operation of a ruby laser has been obtained by the use of a 5° Faraday rotator. Mode selection in a TW ruby laser with electrooptical Q switching is discussed.

Unpolarized EO Q-switched laser
Applied Optics, 1983A novel laser design is given that uses a special polarizing device to generate unpolarized Q-switched laser energy with a conventional EO Pockels cell. The special polarizing device, which replaces the linear polarizer normally used in conventional Q-switched resonators, allows solid-state lasers to operate efficiently at high repetition rates.

Q switched Neodymium:YAG Laser Iridotomy
Ophthalmology, 1984Twenty phakic eyes of 19 patients underwent Q-switched neodymium:YAG laser iridotomies for angle-closure glaucoma. Eleven eyes were previous argon laser failures. Penetration was achieved in each case with several shots in one session. Complications were minor and transient.
