Abstract

A method of controlling output pulses of a pulse laser device (100) including thin-disk laser medium (10), in particular controlling a carrier-envelope phase and/or an intensity noise of the output pulses, includes pumping thin-disk laser medium (10) of pulse laser device (100) with multiple pump laser diodes (21, 22, 23), having at least one modulated laser diode (21, 22) powered by 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), having 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 stable laser diode(s) (23). A pulse laser device (100) is also described.
