Enhanced Cavities for Laser Light | SIMTRUM Photonics Store

Enhancement cavities for continuous-wave/pulsed laser light

Tailored to your setup, the enhancement cavity CALDERA can be built for continuous-wave as well 

as for multi-kW-level average power pulsed operation, serving applications such as the generation

of coherent vacuum-/extreme-ultraviolet (XUV) radiation at repetition rates ofseveral 10s of MHz.

Key Product Features:

 State-of-the-art broadband cavity optics

 Ready for average powers on the 100-kW level

 Advanced designs tailored to specific applications

 Stable operation at repetition rates ≥10 MHz

Femtosecond enhancement cavity: a MHz-repetition-rate pulsetrain is coherently coupled to a passive optical 

resonator via a partially transmitting input coupler, giving rise to a circulating pulse with a power increased by 

up to a few orders of magnitude. The intracavity pulse can be focused to a gas target to generate coherent

vacuum-/extreme-ultraviolet (XUV)radiation at repetition rates of several 10’s of MHz. Coherent XUV radiation 

obtained by cavity-enhanced high-harmonic generation combines high pulse repetition rates with high photon 

energies at high XUV photon flux, and serves a host of time-domain and frequency-domain precision 

metrology applications.
