The laser operates in fundamental mode with beam quality M2 < 1.05 for both beams. The beam shape is recorded at the output of the oscillator (magnified image of the output coupler) on a WinCamD-LCM-NE 1” beam profiler at the nominal operation point of the laser with 3.7 A pump current, approx. 7.8 W total pump power and 440 mW average output power from each comb.

Single laser emits high-power dual comb femtosecond pulses

The new development paves the way for portable dual-comb light sources for applications such as spectroscopy and precision distance measurement
