MOGLabs 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, MOGLabs 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.
