Description
High-efficiency frequency doubling with robust, alignment-free operation
The MSL series from Santec provides highly efficient second harmonic generation (SHG) across a wide range of wavelengths. Based on a monolithic linear cavity design, MSL systems deliver stable, high-performance frequency conversion without the alignment sensitivity of traditional bow-tie cavities.
Designed for both standalone operation and integration with amplified laser systems, the MSL enables reliable access to new wavelengths with minimal user intervention.
Monolithic linear cavity design
No kinematic adjustments required, ensuring long-term stability and alignment-free operation.
Broad wavelength coverage
Supports a wide range of fundamental/harmonic pairs, including:
740/370nm, 798/399nm, 922/461nm, 960/480nm, 1020/510nm, and more.
Fully integrated control system
Includes temperature stabilisation and PDH (or FM) locking with integrated digital control—no external controller required.
Flexible system configurations
Available as a complete standalone doubler or integrated with our laser and amplifier systems.
Applications
- Generation of visible and UV wavelengths from IR sources
- Atomic physics (Sr, Yb, Rb, Cs transitions)
- Precision spectroscopy
- Quantum optics and sensing
- Nonlinear optics and wavelength conversion
System Integration
MSL systems can operate as standalone frequency doublers or be integrated with external seed lasers and amplifiers. Fibre input/output options and built-in control electronics simplify integration into both laboratory and OEM environments.
