Enhanced spontaneous Raman scattering technique for highly luminous environments
Description:
A gated photon counting system, cavity-dumped argon ion laser, and a multipass retro-reflecting light cell have been combined in a system to enhance spontaneous Raman scattering in luminous background situations. Signal-to-background ratio (S/B) has been improved a factor of 450 over a single-pass cw system with cw power equal to the pulsed average power. The improvement attributable to the gating and cavity dumping the laser is a factor of 30. A factor of 15 improvement is due to the retro-ref…
