Linear cavity SHG system (MSL)

The MOGLabs MSL linear cavity SHG system allows highly efficient frequency doubling of laser light over a broad wavelength range, including 740/370, 798/399, 840/420, 922/461, 960/480, 1020/510, and 1107/553nm. Unlike bow-tie ring cavities, the linear design requires no alignment adjustment. SHG efficiency is typically 80 to 90% for mid-power TA amplified systems (0.5 to 5 watts), and can be optimised for low power direct ECDL (e.g. 100mW) or high power fibre amplified systems.

The cavity is monolithic, with temperature stabilisation and a high-bandwidth piezo actuator for locking. The MSL is available separately as a complete doubling system with input mode matching, PDH (or HC) locking, fibre input and fibre output, or combined with MOGLabs optical or fibre amplified lasers, to provide stable and robust sources for new wavelengths.

The MSL uses a variant of our MLC mini laser controller as the headboard for cavity control and communications.
