发明名称 Method for operating a laser system
摘要 In a method for operating a laser system in a Q-switched mode, the laser system provided with a laser resonator with a laser medium and an electro-optical modulator, wherein the electro-optical modulator has an EOM crystal, wherein the EOM crystal has a characteristic ringing time (t0) when subjected to acoustic ringing, the EOM crystal is driven by modulator voltage pulses (pm) having a modulator voltage pulse duration (tml). A train of at least two subsequent laser pulses (pl) is generated. The modulator voltage pulse duration (tml) is selected to be at least approximately equal to the characteristic ringing time (t0) of the EOM crystal multiplied by an integer factor.

主权项 1. A method for operating a laser system in a Q-switched mode, the laser system comprising a laser resonator with a laser medium and an electro-optical modulator, wherein the electro-optical modulator comprises an EOM crystal, wherein the EOM crystal has a characteristic ringing time (t0) when subjected to acoustic ringing, the method comprising: driving the EOM crystal by modulator voltage pulses (pm) having a modulator voltage pulse duration (tml); generating a train of at least two subsequent laser pulses (pl); selecting the modulator voltage pulse duration (tml) to be equal to the mathematical product of the characteristic ringing time (t0) of the EOM crystal and of an integer factor with a tolerance of no more than ±25% of the characteristic ringing time (t0).
