SHG pro – Stand-Alone Second Harmonic Generator Module
- Frequency doubling of Ti:Sapphire, dye, gas, fiber and diode lasers
- Compact, stand-alone bow-tie cavity
- pro technology for highest mechanical and thermal stability
- Highest cw conversion rates
- Near TEM00 beam profile
- Mode matching and beam shaping optics integrated
- Optional fiber coupling of input and/or output beam
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.
