SHG pro
Frequency-doubling unit
• Compact module for resonant frequency doubling
• Best cw conversion rates
• Wavelengths: 190 .. 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 190 to 800 nm. TOPTICA offers competent support for adapting the unit to customer requirements.
Applications
• Frequency-doubling of existing TOPTICA diode lasers
• Frequency-doubling of 3rd party lasers
(single-frequency lasers, e.g. Ti:Sapphire, Cr:LiSaF, dye lasers, gas lasers, DPSS, diode and fiber lasers)Options
• FiberDock SHG input: Fiber coupling of fundamental (input) beam (recommended)
• Double Piezo Lock: High-bandwidth stabilization of the SHG pro resonator
• FiberDock SHG: Fiber coupling of SHG output beam
• EOM/SHG pro: Electro-Optic Modulator for error signal generation (Pound-Drever-Hall method)
