A laser apparatus and method is disclosed comprising a first lasant material which is located in an optical cavity and which produces laser radiation of a first wavelength, and a second lasant material which is pumped by radiation from the first lasant material, which absorbs laser radiation at the first wavelength in an amount generally comparable to the Optimum Output Coupling, which functions as the output coupler for the optical cavity and which lases at a second wavelength. The first lasant material and the second lasant material are preferably selected to have minimal losses such that there is a net gain in the cavity.

A laser apparatus, comprising: a) a first laser cavity; b) a first lasant material which is located in said first laser cavity to produce optical radiation at least at a primary laser wavelength; and c) a second lasant material which is optically pumped by said optical radiation from said first lasant material, which absorbs optical radiation at said primary laser wavelength in an amount to achieve Optimum Output Coupling to said optical radiation from said first lasant material, which is at least partially located in said first laser cavity, which functions as the output coupler of said first laser cavity, and which lases at a secondary laser wavelength, said second lasant material being selected to have sufficiently low excited-state absorption losses at said primary wavelength such that there is a net gain in said first laser cavity.
