The MOGLabs Optical amplifier for external seed – MOA/MOAL / MOAC are compact, robust and stable tapered amplifier systems, for wavelengths from 650 to 1080nm, at power up to 5W.
The MOGLabs Optical amplifier for external seed – MOA/MOAL / MOAC are compact, robust and stable tapered amplifier systems, for wavelengths from 650 to 1080nm, at power up to 5W.
Three versions are available. The full-size MOA provides all the capabilities of the MSA, including provision for single or double-stage isolators on the input and output, and free-space or fibre-coupled input and output. The MOAL is a streamlined chassis for those not needing an isolator on the input. The MOAC is very compact for the do-it-yourself researcher, without provision for internal isolators.
All three versions feature the same wire-cut flexure mounts used in our MSA system, for both input and output coupling lenses, to provide outstanding passive stability and simple user-replacement of the TA diode if necessary. Using carefully designed optics, MOGLabs achieves very high 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 output can be divided into two beams, one free-space and the other free-space or fibre-coupled.
Replacement of the amplifier diode and alignment are easily accomplished by the end-user. Options include 35 or 70dB of output isolation and 35dB on the input (wavelength dependent), and fibre coupling of input or output or both. Wavelength options extend from 650nm to 1140nm, and power from 250mW to 5000mW.
Also available in the MOA larger chassis size for more input isolator options, or as a cateye laser seeded amplifier MSA.
