Enhancement of Stokes conversion by diode-laser injection in a para-H(2) Raman laser.
The injection effect of weak Stokes seed radiation is demonstrated in a para-H(2) Raman laser. Injected radiation from a PbSnTe diode laser as low as several microwatts resulted in an enhancement of 4 orders of magnitude in the output Stokes energy and a reduction in the pumping threshold energy of 22%. Characteristics of the injection are investigated as functions of the pumping energy, the Stokes seed frequency, and the polarization.
