SHG pro
- Compact module for resonant frequency doubling
- Best cw conversion rates
- Wavelengths: 205..800nm, linewidth < 500 kHz
- Highest stability and Ease of Use: pro technology
- For Ti:Sapphire, dye, gas, fiber and diode lasers
The SHG pro is the device of choice if existing lasers are to be frequency doubled. Designed in TOPTICA’s pro technology, it unites highly stable performance and convenient operation. Mirror and crystal holders can be adjusted without opening the resonator cover. A wide range of non-linear crystals covers SHG wavelengths from 205 to 800 nm. TOPTICA offers competent support for adapting the unit to customer requirements.
