Q-switch

English Etymology The Q stands for the quality factor of the resonator on the laser. Noun ~ A device that causes Q-switching. en Q spoiler en 2003 Laser Material Processing W. M. Steen; Kenneth Watkins 29 Around 60-100 W is required to deflect a 60 W beam and hence the Q-switch has to be cooled. en 2009 Soviet Laser Physics - Volume 19 1404 The Q-switch was placed at the beam waist of the resonator as mentioned before. en 2014 Laser-Induced Damage in Optical Materials Detlev Ristau 3 The invention of the Q-switch quickly followed the invention of the laser discovered in 1961 and published in 1962 [3]. The process of Q-switching. en 2012 Nonlinear Optics and Solid-State Lasers Jianquan Yao; Yuyue Wang Also, the appearance of Q-switch and ultra-short pulse technology made the peak power improve greatly, and the efficiency of doubling reached 70-80%. en 2014 Laser Physics: From Principles to Practical Work in the Lab Marc Eichhorn 75 The general temporal evolution of the Q-switch is sketched in Fig. 4.2 for the case of an active Q-switch that acts on the internal cavity losses Λ. en 2018 Photoacoustic Tomography Huabei Jiang 109 We see that the timer/controller contains a 10 Hz laser Q-switch signal repeated each 100 ms (the Q-switch pulse width is 100 μs, and the lasar pulse with is 10 ns). Verb en transitive To use a Q-switch on (a laser). en 2001 Rare-Earth-Doped Fiber Lasers and Amplifiers Michel J.F. Digonnet A variety of methods are available to Q-switch a fiber laser. Most of them are adaptations of those used to Q-switch bulk lasers. en 2011 Fundamentals of Light Sources and Lasers Mark Csele 295 The ability to Q-switch this laser results in fast, intense pulses of red light that cannot be generated by other means. en 2013 Solid-State Laser Engineering Walter Koechner 505 In order to Q-switch an unpolarized laser system, such as Nd:YAG, the lower of the efficiency factors of a longitudinal device determines the extinction ratio of the device.
