Increased reliability of passive mode-locking a multi-atmosphere TE CO2 laser by injection mode-locking [PDF]
, 1986 By injection of manosecond pulses from an AM mode-locked TEA CO2 laser in a passive mode-locked multi-atmosphere TE CO2 laser the shot-to-shot reproducibility of the generated subnanosecond pulses was increased to almost 100%
