Solid-state dye laser

In the 1990s, new forms of improved PMMA, such as modified PMMA, with high optical quality characteristics were introduced.^[3] Gain media research for SSDL has been rather active in the 21st century, and various new dye-doped solid-state organic matrices have been discovered.^[4] Notable among these new gain media are organic-inorganic dye-doped polymer-nanoparticle composites.^[5][6][7] An additional form of organic-inorganic dye-doped solid-state laser gain media are the ORMOSILs.^[7][8]

This improved gain medium was central to the demonstration of the first tunable narrow-linewidth solid-state dye laser oscillators, by Duarte,^[8] which were later optimized to deliver pulse emission in the kW regime in nearly diffraction limited beams with single-longitudinal-mode laser linewidths of ${\displaystyle \Delta \nu }$ ≈ 350 MHz (or ${\displaystyle \Delta \lambda }$ ≈ 0.0004 nm, at a laser wavelength of 590 nm).^[9] These tunable laser oscillators use multiple-prism grating architectures^[9] yielding very high intracavity dispersions that can be nicely quantified using the multiple-prism grating equations.^[10]

Additional developments in solid-state dye lasers were demonstrated with the introduction of distributed feedback laser designs in 1999^[11][12] and distributed feedback waveguides in 2002.^[13]
