Flashtube-Pumped Dye Laser with Multiple-Prism Tuning

Abstract

A four-prism tuning system has been built and tested in a flashtube-pumped rhodamine 6G dye-solution laser. Equations for calculating reflection losses and prism dimensions are given, and performance characteristics of the tuned laser are presented. The half-power points of the tuning range were 571 nm and 615 nm, and the output bandwidth at peak power was 0.17 nm at half-maximum. The energy output at 595 nm was 0.14 J.

Tunable organic dye lasers

“…Figure taken from Strome and Webb (7) straining possible laser action to this specified (low-loss, retroreflected) wavelength is equivalent to choosing a specific, constant-wavelength plane in Figure 4.…”

“…Tuning is accomplished simply by rotating the grating or the cavity mirror adjacent to the prism, so a different wavelength will become the retroreflected, low-loss wavelength for the dispersive cavity. Figure 5 shows the tuning range of a prism-tuned, flashlamp-pumped rhodamine 6G dye laser (7).…”

Low-loss wavelength tuning of a mid-infrared Cr2+:ZnSe laser using a Littrow-mounted resonant diffraction grating

“…Controlling and tuning the emission wavelength of lasers with a broad gain spectrum has been a widely researched topic already for many decades [1]. Various configurations have been proposed, many of them relying on the implementation of prisms and/or diffraction gratings inside the laser cavity [2,3]. While the use of prisms is preferred in case low intra-cavity losses are required, one opts for diffraction gratings when a high wavelength selectivity is needed [1].…”
