Q-switched operation of microchip lasers
Optics Letters, 1991With a novel Q-switching technique, 6-ns output pulses are produced from a single-mode Nd:YAG microchip laser pumped with 120 mW of cw optical power. Rate-equation analysis indicates that with a pump power of 500 mW, Q-switched Nd:YAG microchip lasers having subnanosecond pulses and peak powers of several kilowatts are feasible.

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-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.

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.

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-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.

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.

The Q-switched Ruby Laser in Glaucoma
Ophthalmology, 1984A pilot study evaluated the safety and effectiveness of a Q-switched ruby laser in the treatment of both pupillary-block (10 eyes) and open-angle glaucoma (4 eyes). All patients had either poor visual acuity or had previously failed with conventional surgery. We created a patent iridotomy in all eyes, with one pulse in eight.
