Abstract: | Outputs at two wavelengths with orthogonal polarizations are generated in a N2-laser pumped dye laser by a simple method. The light leaving the laser cavity at the side exit of the polarizing Glan-Thompson is redirected into the cavity via an additional mirror and a second Glan-Thompson. Depending on its polarization light is travelling different paths and may hit the grating at different angles. In this way feedback is produced for two separate light beams and lasing can take place at two wavelengths simultaneously. |
