Single-mode pulsed tunable dye laser
Abstract
The design and performance of a tunable single-mode optically pumped grazing-incidence pulsed dye laser are reported. The device is a modified version of the laser described by Littman and Metcalf (1978) and Liu and Littman (1981) and comprises a 2-mm-path-length dye cell, a 1.27 x 2.5-cm 2400 line/mm diffraction grating, two 2.5-cm-diameter lambda/20 dielectric mirrors, a 4-in.-diameter rotation stage, a 100-nm-resolution differential micrometer, three 2.5-cm-square mounts, a 2.5-cm-diameter 750-mm lens, and a translation stage. Performance parameters include time-averaged linewidth less than 150 MHz, near-TEM(00)-mode operation, tuning range greater than 15/cm without mode hopping, background light less than 0.01 percent, and efficiency 3 percent. A drawing of the apparatus, Fizeau interferograms of the scanning pattern, and a photograph showing the spatial mode of the laser are provided.
