Abstract

A solid-state dye laser and technique for achieving multiple output wavelength laser emission from a single solid-state dye laser media containing multiple dyes without tuning elements. When the multiple dyes within the single solid-state host are excited with a single wavelength pump source to lase, there results simultaneous multi-spectral output proportional to dye concentration ratios.

Claims

1. A technique for achieving multiple output wavelength laser emission from a single solid-state dye laser media, said single solid-state laser media containing multiple dyes having predetermined dye concentration ratios, said technique comprising:

doping a dye medium with multiple dyes having predetermined dye concentration ratios into an optical solid-state host;

incorporating said optical solid-state host within a cavity means of a laser oscillator;

applying pump energy to said optical solid-state host to excite a minimum of at least one of the dyes to effect laser output from said laser oscillator whereby additional dye to dye interactions within the solid-state host are excited to produce multiple laser emissions of simultaneous multi-spectral outputs proportional to said predetermined dye concentration ratios.

2. A solid-state dye laser for achieving multiple output wavelength laser emission from a single solid-state dye laser media, said single solid-state laser media containing multiple dyes having predetermined dye concentration ratios, said laser comprising:

a cavity means which defines a laser oscillator;

an optical solid-state host within said cavity means, said optical solid-state host containing multiple dyes with predetermined dye concentration ratios;

means for applying pump energy to said optical solid-state host to effect laser output created from dye to dye interactions from said laser oscillator whereby the multiple dye molecules within the solid-state host are excited to lase simultaneous multi-spectra outputs proportional to said predetermined dye concentration ratios.
