Paper Abstract

Q-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 requirements. Emphasis will be placed on providing practical limits of operation to guide systems design. These include alignment sensitivity, voltage/power requirements, laser induced damage, the effects of extreme temperature, shock and vibration, mechanical mounting strain, and piezoelectric driven ringing. An example of a new Q-switch suitable for mid-IR lasers, which may improve ignition, will be described.
