Method and device for controlling a carrier-envelope phase and/or an intensity of output pulses of a pulse laser device

摘要

A method of controlling output pulses of a pulse laser device (100) including a thin-disk laser medium (10), in particular controlling a carrier-envelope phase and/or an intensity noise of the output pulses, includes the steps of pumping the thin-disk laser medium (10) of the pulse laser device (100) with multiple pump laser diodes (21, 22, 23), which include at least one modulated laser diode (21, 22) which is powered by a current source (31, 32) with modulation capability, and controlling the output pulses by modulating the output power of the at least one modulated laser diode (21, 22), which is modulated by controlling a drive current thereof, wherein the pump laser diodes further include at least one stable laser diode (23), which has a constant output power, and the output power of the at least one modulated laser diode (21, 22) is smaller than the whole output power of the at least one stable laser diode (23). Furthermore, a pulse laser device (100), being adapted for creating output pulses, in particular having a controlled carrier-envelope phase and/or intensity noise, is described.
