CALDERA — Enhancement Cavity (CW and Multi-kW Pulsed; Tailored to Your Setup)
Design Tools
CALDERA is an enhancement cavity tailored to your setup, supporting both continuous-wave (CW) and multi-kW-level average-power pulsed operation.
Built around UFI's ultra-low-loss optical-coating technology and precision opto-mechanics, CALDERA enables coherent power buildup for nonlinear conversion, intracavity HHG, gravitational-wave-detector R&D, optical-frequency-comb stabilization, and resonant absorption spectroscopy.
Key Product Features
- Tailored to your laser source and experimental geometry
- CW and pulsed operation supported (single device)
- Multi-kW intracavity average power capability
- Single-ppm-loss mirrors (compatible with UFI's GLACIER-characterized coatings)
- Customizable mirror coatings for desired wavelength range
- Active or passive locking (PDH / fringe-side / dither)
- Compact bench-top to vacuum-compatible configurations
Applications
- Intracavity high-harmonic generation
- Frequency-comb stabilization & spectroscopy
- Gravitational-wave-detector mirror R&D
- Resonant absorption / cavity-enhanced spectroscopy
- Power-buildup for nonlinear conversion
Developed at the Max-Planck-Institute of Quantum Optics. UFI is a spin-off from LMU Munich and the Max Planck Society.
