Abstract

The stimulated Raman scattering detection apparatus includes first and second light pulse generators ( 1, 2 ) respectively generating first and second light pulses with first and second pulse periods, an optical system combining the first and second light pulses and focusing the combined light pulses onto a sample, and a detector ( 10 ) detecting the second light pulses intensity-modulated by stimulated Raman scattering generated by focusing of the combined light pulses onto the sample. The second light pulse generator divides each raw light pulse emitted with the second pulse period into two light pulses, delays one of the two light pulse with respect to the other thereof and combines the one light pulse divided from one raw light pulse and delayed, with the other light pulse divided from another raw light pulse emitted after the one raw light pulse, to generate the second light pulse.

First claim

The invention claimed is:

1. A stimulated Raman scattering detection apparatus comprising:
a first light pulse generator configured to generate first light pulses with a first pulse period;
a second light pulse generator configured to generate second light pulses with a second pulse period shorter than the first pulse period, the second light pulse having a light frequency different from that of the first light pulse,
an optical system configured to combine the first and seco…
