MOA/MSA Optical Amplifier/Seeded Amplifier

The MOGLabs Optical Amplifier is a high-power extension for single-frequency external cavity diode lasers.

Laser power is increased by up to 4W, while maintaining the tunability and linewidth of the injection seed laser.

Replacement of the amplifier diode and alignment are easily accomplished by the enduser. Options include 35 or 70dB of input isolation and 35dB on the output, and fibre coupling of input or output or both. Wavelength options extend from 630nm to 1064nm, and power from 250mW to 3000mW.

Also available as cateye laser seeded amplifier MSA as shown.


  • Wavelength 630nm – 1064nm
  • Output power up to 3W
  • Optional input and output Faraday isolators
  • Optional input and output fibre coupling
  • Simple customer TA diode replacement
  • Stable flexure alignment


  • Laser cooling and trapping
  • Bose-Einstein condensation
  • Quantum optics: squeezed light
  • Electromagnetic transparency and slow light
  • Time and frequency standards
  • Laser spectroscopy
  • Physics teaching labs
