Description
Flexible, high-efficiency optical amplifiers for custom laser systems
The MOA and MOAL series from Santec are compact tapered amplifier systems designed to boost optical power while maintaining beam quality and efficiency. Supporting wavelengths from 650nm to 1080nm, these systems deliver up to 4 W output power with flexible input/output configurations.
Available in two form factors, MOA and MOAL provide scalable solutions for both fully featured laboratory setups and space-constrained environments.
High coupling efficiency
Optimised optical design enables operation with low seed input power (few mW), depending on wavelength and output requirements.
Flexible system configurations
Supports free-space or fibre-coupled input/output, with options for beam splitting and dual outputs.
Robust, stable optomechanics
Wire-cut flexure mounts ensure excellent passive stability and alignment retention.
User-serviceable design
Tapered amplifier diode can be replaced, minimising downtime.
Two form factors for different needs
- MOA: Full-featured system with support for internal isolators (single or double-stage)
- MOAL: Compact chassis for space-constrained setups (no internal input isolator)
Applications
- Power scaling of external seed lasers
- Nonlinear optics and frequency conversion
- Quantum optics and atomic physics
- Spectroscopy and sensing systems
- OEM and custom photonics integration
System Integration
MOA and MOAL amplifiers are designed to integrate seamlessly with external seed lasers, including tunable diode lasers and fibre systems. Flexible input/output options and beam splitting capabilities allow easy incorporation into complex optical setups or custom-built systems.
