Spectrally narrow pulsed dye laser without beam expander

Abstract

We have developed a simplified version of the side-pumped pulsed dye laser which has a spectral halfwidth of 1.25 GHz and a peak power of 10 kW at 600 nm. The basic laser consists of only four components (output mirror, dye cell, diffraction grating, and tuning mirror) and is exceptionally easy to align. Since the beam expander has been eliminated, the laser cavity can be made quite compact. Under the condition of reduced gain, the laser has been operated in a single mode.

External cavity wavelength tunable semiconductor lasers - a review

“…5. They are named Littrow (due to the Littrow retro-diffraction geometry) and Littman or grazing-incidence configurations (sometimes referred to as Littman/Metcalf's [56,57]). The lasing wavelength in each of these designs is determined by the centre of the grating dispersion curve, which is given by the well-known grating equation…”

Multi-Wavelength Fiber Optical Parametric Oscillator Based on a Highly Nonlinear Fiber and a Sagnac Loop Filter

“…This year we welcome the 50th anniversary of the laser technology, which has powered remarkable progress [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] in the past 50 years since the invention of the first laser in 1960 [19]. Fiber lasers are one kind of the most important lasers, which also include multi-wavelength fiber lasers (MWFLs) with a huge potential in applications such as WDM optical communication systems, optical fiber sensors, optical component testing, microwave photonics and spectroscopy [20][21][22][23].…”
