1963New Scientist 24 Oct. 201/2 A technique known as ‘Q-spoiling’ is used to store the laser's energy and liberate it in brief but tremendous bursts. 1966Appl. Physics Lett. IX. 285 A technique involving the use of a magnetic field in ‘Q’-spoiling a ruby laser cooled to 77°K is discussed. 1970Physics Bull. Mar. 116/2 By temporarily ‘Q-spoiling’ the laser resonator by inserting a Kerr cell shutter between the high reflectivity mirror and the ruby laser rod, the energy storage capacity of the ruby was increased above the level at which relaxation oscillation would normally begin. Ibid., By 1965 powers of 109 W in pulses of duration ∼ 10 ns were produced by following the Q-spoiled oscillator with a series of ruby amplifiers. 1975D. G. Fink Electronics Engineers' Handbk. xi. 13 The typical output of an optical laser consists of a series of spikes occurring during the major portion of the time that the laser is pumped... Q switching (Q spoiling) is a means of obtaining all the energy in a single spike of very high peak power. |
