GENERATION OF STIMULATED-EMISSION BY VISIBLE MULTIPHOTON DISSOCIATION OF PBCL2 MOLECULES

Stimulated emission was generated at the 722.9nm line of neutral lead atoms by multiphoton dissociation of PbCl2 molecules with a DPS dye laser. Anti-Stokes Raman scattering around 283.3nm was also observed. The effects of the heat-pipe oven temperature and pump laser energy on the 722.9nm radiation was studied. The energy conversion efficiency of the 722.9nm laser is about 5%. It provides a way for frequency conversion by multiphoton dissociation of simple molecules with a visible laser.
