Dye amplifier

We have performed Raman echo experiments using synchronously pumped dye lasers, followed by dye amplifiers pumped by a Q-switched Nd YAG laser (Fig. 7). These systems are standard (127-129), but several...

The originally doubled, Nd-YAG (2 x Nd-YAG) laser beam at 532.0 nm is directed through a KG-3 filter to remove any 1.06-um energy. Part of this laser beam is used to excite the dye in the dye-laser amplifier cell. Usually about 30% of the originally doubled ND-YAG beam is used for dye pumping and the residual 70% is directed to the CARS test section. The dye amplifier cell (DC) is at Brewster s angle to maintain the horizontal polarization of the dye-laser beam.
