High-power amplification up to 5W
Efficiently scales seed laser power for demanding applications.
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.
The MOAL / MOA are compact, robust and stable tapered amplifier systems, for wavelengths from 650 to 1080nm, at power up to 4W.
Two versions are available. The full-size MOA allows for single or double-stage isolators on the input and output, and free-space or fibre-coupled input and output. The MOAL is a narrower chassis which does not allow for an internally mounted isolator on the input.
Both MOAL and MOA options feature the same wire-cut flexure mounts used in our MSA system for input and output coupling lenses, to provide outstanding passive stability and simple user-replacement of the TA diode if necessary. Using a carefully designed optical system, it achieves very high TA coupling efficiency such that the seed input power can be just a few mW, depending on wavelegth and output power.
For MOA and MOAL, the amplified output can be divided into two beams, one free-space and the other free-space or fibre-coupled.
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.
