CVFL-MEGA are based on a MOPFA design, they integrate a low noise and narrow linewidth seed laser which is amplified through several fiber amplifier stages. The output is then frequency converted to visible wavelength by a single pass periodically-poled crystal.
The lasers can be thermally and current tuned in order to lock their wavelength on saturated absorption.These lasers are renowned for their robustness, reliability and maintenance free operation.
The laser might be controlled by using touch-screen interface, or Ethernet control software
or TTL signals.
