The output laser power is measured by an thermal detector (Ophir VEGA) at the output fiber end through a Sapphire filter. The filter is a dichroic mirror used to get rid of the pump power at 1.5 microns.

The incident pump power is measured before the gain fiber by the same thermal detector. The absorbed pump power is the pump power at P(9) line which is absorbed by acetylene.

The lasing threshold is the measured incident power when the laser power at 3 micron can be just detected by the themal detector(Ophir VEGA). The minimum detectable power at 3 micron is about 1 mW.
