A device for generating laser radiation comprises a temperature-controlled optical setup comprising an optically non-linear solid state medium arranged in a resonator and an active region. The outgoing laser radiation is generated from a pump beam introduced into the optically non-linear solid state medium. A first temperature actuator and a second temperature actuator configured to independently adjust temperature values in the active region of the optically non-linear solid state medium. The first temperature actuator is configured regulate a length of the resonator by setting a first temperature value within a first portion of the active region. The second temperature actuator is configured to match phases of wavelengths generated by the outgoing laser radiation and phases of wavelengths of the pump beam radiation by setting a second temperature value within a second portion of the active region.
