A ruby laser was Q-switched by means of a plasma. The plasma, which had a density of up to 10(18) cm(-3), was produced in an electromagnetic shock tube. The density gradient created by the reflected plasma was large enough to produce measurable refraction of the laser beam. The laser cavity, which was initially misaligned, attained perfect alignment when the plasma was introduced into the cavity.
利用等离子体对红宝石激光器进行调Q。在电磁激波管中产生了密度高达10¹⁸厘米⁻³的等离子体。反射等离子体产生的密度梯度足够大，能使激光束产生可测量的折射。最初未对准的激光腔在将等离子体引入腔内时实现了完美对准。
