Abstract

A variation of the grazing-incidence pulsed dye laser is presented. This laser has been operated in a single longitudinal cavity mode with a single-shot linewidth of less than 300 MHz and a time-averaged linewidth of 750 MHz. The single-mode conversion efficiency of the laser is 2% using Rhodamine 6G dye.

Analysis of laser output using 7.5-GHz FSR scanning Fabry–Perot etalon: (a) single-mode operation—the measured linewidth is limited by shot-to-shot laser jitter. The single-shot linewidth is at most 300 MHz; (b) the laser has been misadjusted to demonstrate multimode operation. The observed mode separation agrees with the value expected for an 8-cm cavity.
