Description
Turnkey high-power frequency-doubled laser systems
The MSHG series from Santec combines a seed laser, optical amplifier, and high-efficiency SHG cavity into a single integrated platform. Designed for maximum performance and ease of use, MSHG systems provide stable, high-power output at wavelengths that are otherwise difficult to access.
Using the same robust monolithic linear cavity design as the MSL, MSHG systems eliminate alignment complexity while delivering consistent long-term performance.
High conversion efficiency
Typically 50–60% overall efficiency for amplified systems, with optimisation up to ~70% for lower-power inputs.
Monolithic, alignment-free cavity
Ensures stable operation without the need for user adjustment.
Optimised for key atomic wavelengths
Common outputs include:
399nm (Yb), 420/480nm (Rb), 461nm (Sr), 510nm (Cs)
Integrated digital control
Includes temperature control and PDH/FM locking with built-in electronics—no external controller required.
Applications
- Laser cooling and trapping (Sr, Yb, Rb, Cs)
- Optical clock systems
- Quantum optics and atomic physics
- Precision spectroscopy
- High-power visible/UV laser generation
System Integration
MSHG systems are designed as turnkey solutions but can also be configured with external seed lasers via fibre input. Dual outputs allow monitoring of both the fundamental and harmonic signals, supporting advanced system diagnostics and integration.
