Description
ModeMIR is a compact, turn-key operated system generating broadband mid-infrared radiation in the range from 3 to 10 µm. Suited for most demanding scientific applications, like optical frequency comb spectroscopy, astrophysics and astrochemistry.
Main features:
- Mode spacing / pulse repetition rate: between 100 and 125 MHz
- Spectral coverage from 3 to 10 µm
- Tunable repetition rate option available
- Electro-optical modulator option for PDH locking
- Automatic output power locking
- Automated wavelength tuning
- Optional offset frequency (f0) tuning available
- Self-starting, maintenance-free, button-operated
- Single-box solution
