Description
High-power, fully integrated seeded laser systems with exceptional stability
The MSA series from Santec combines a narrow-linewidth seed laser with a tapered amplifier on a single, compact platform. Designed for high-power applications, MSA systems deliver up to 5W of optical output while maintaining excellent spectral performance and long-term stability.
Built around our inherently self-aligning cateye seed laser, the MSA provides low frequency drift and reliable operation, making it well suited to demanding precision experiments and advanced photonics systems.
High output power
Delivers up to 5W optical output, enabling demanding applications and downstream conversion stages.
Exceptional passive stability
Wire-cut flexure mounts for coupling optics ensure long-term alignment stability and consistent performance.
User-serviceable amplifier design
Tapered amplifier (TA) chip can be replaced by the user, reducing downtime and cost of ownership.
Flexible isolation options
Supports a wide range of optical isolators, including compact and double-stage configurations.
Applications
- Laser cooling and atomic physics (e.g. Sr, Yb systems)
- Precision spectroscopy and metrology
- Nonlinear optics and frequency conversion (SHG, SFG, DFG)
- High-power seeding for advanced laser systems
- Quantum technologies and research
System Integration
MSA systems provide a complete high-power laser platform, eliminating the need for separate seed and amplifier components. They can be used as standalone sources or integrated with nonlinear conversion modules to access visible and UV wavelengths, with flexible options for isolation and beam delivery.
