K. Sasaki et al., INJECTION SEEDING FOR SINGLE-MODE OPERATION IN AN OPTICALLY PUMPED HIGH-POWER D2O LASER, International journal of infrared and millimeter waves, 16(12), 1995, pp. 2133-2146
Spectrally narrow, pulsed outputs consisting of almost a single mode h
ave been obtained from an optically-pumped high-power (200 kW) D2O las
er by adopting the injection seeding method, where single-mode radiati
on (seed pulse) from a low-power, compact D2O laser has been injected
into the main D2O laser. Spectrally narrow outputs with high power hav
ing spectral widths as narrow as 5 MHz have been obtained, when the se
ed pulses with frequency tuned to one longitudinal mode of the main D2
O laser have been injected at a time sufficiently before the lasing of
the main laser took place. The experimental results have been compare
d with those of numerical simulation modified to include the injection
field with varying injection times.
