[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
[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.
