Vitreolysis With the Q-Switched Laser
Archives of Ophthalmology, 1985We present an overview concerning the current status of photodisruptive methods used in the treatment of pathologic changes in the vitreous space. In one series of 320 cases studied, 65% of the planned dissections of pathologic structures were successful. In a second series of 34 more complicated cases, the success rate was even lower.

Q-Switch Modulator as a Pulse Shaper in Q-Switched Fiber Lasers
IEEE Photonics Technology Letters, 2012An experimental study of several operation regimes of Q-switch modulator and their impact on the shape of Q-switched fiber laser pulses are discussed. It is shown that various Q-switch regimes including classical Q-switch, simultaneous Q-switch with quasi-mode-locking, or Q-switch with reduced interval between subpulses can be easily obtained using ...

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.

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-switching the Erbium-YAG Laser
Journal of Modern Optics, 1994An erbium-YAG laser has been Q-switched by two methods; a mechanical technique employing a rotating output coupler and electro-optically utilizing a LiNbO3 crystal. The performances of each technique are assessed and compared. Pulse durations of 150 to 850 ns have been produced, with pulse energies of 1 to 16 mJ depending on the technique used.

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.
