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.

Q-switching is a method to generate laser pulses with a short pulse duration and high peak power. In this method, the fast, giant pulse is generated by allowing the pumping process to build up a population inversion and gain inside the laser cavity without oscillations, which are larger than the normal values under free-running operation. This is done

IEEE Circuits and Devices Magazine, 2003
Passively Q-switched, diode pumped, all solid-state lasers are an elegant, yet simple, means to generate single-frequency laser pulses in the nanosecond and sub-nanosecond regions. The majority of the work on these systems has been in the 1-/spl mu/m region, but recent developments at eye-safe and mid-infrared wavelengths of both diode-pumped lasers ...

Q-switching technologies: limitations and opportunities: finding the right Q-switch
SPIE Proceedings, 2009Q-switches for laser ignition applications must meet a unique set of requirements. The inherent challenges to providing extremely reliable, compact, practical, and cost effective devices are daunting. The capabilities and limitations of various passive and active technologies will be explored and compared against generic laser driven ignition ...

So far we have investigated SMBS under conditions that exclude the influence of the scattered light on the operation of the exciting-radiation generators. It is of interest also to consider another situation, where there is a strong coupling between the scattering medium and the source of the exciting light (the laser).
