1963 New 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.
1975 D. 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.
2004 G. A. Rinard et al. in L. J. Berliner & C. J. Bender EPR: Instrumental Methods iii. 150 This could be done with a combination of a crossed-loop resonator.., active Q-spoiling.., and..pulse cancellation.
