Fully integrated seed + amplifier system
Combines a stable cateye seed laser with a tapered amplifier for a complete, turnkey high-power solution.
Description
The tunable lasers can be combined with optical amplifiers or fibre amplifiers for direct wavelength amplification, or with frequency converted systems to access second harmonics and sum or difference frequency mixing.
For Sr/Yb clock systems see:
Injection-Locked Amplifiers: 800mW at 461nm, >200mW at 399nm
Linear Cavity SHG systems: 1W at 461nm, 399nm
The MSA series of amplified lasers provides a compact, robust, stable system with integrated seed laser and tapered amplifier diode to provide up to 5W of optical output.
The design features wire-cut flexure mounts for the input and output coupling lenses, which provide outstanding passive stability as well as easy user-replacement of the TA chip after reaching end-of-life.
A wide range of isolators can be used, including compact isolators with 4mm aperture, through to double-stage isolators with 5mm aperture.
The MSA seeded amplifier uses the unique inherently self-aligning cateye laser with its very low frequency drift and industry-leading low passive linewidth.
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.
