Dynamic behavior of CO₂ lasers

Dynamic behavior of CO₂ lasers

Spontaneous pulsations have been observed in the output of a CO2 laser. The temporal waveforms, transverse mode patterns, and laser lines are simultaneously measured under various operation conditions. The experimental data show that these pulsations have a direct connection with the transverse mode...
