摘要：
It is an object of the invention to provide a simple setup of a waveguide laser which allows to control the emission of specific laser wavelengths in a laser material having laser transitions of similar wavelengths. For this purpose a core (4) forming a gain medium is provided with a cladding (6) which introduces losses to an undesired laser transition but is transparent to the light of a desired laser transition. A second cladding (8) is provided for guiding the laser radiation. Pr: ZBLAN with a Tb: doped cladding may be used. Instead of the absorbing cladding (6) a photonic crystal (20) may be used. The laser is end-pumped by a laser diode (14).
