Diode laser pumped multimode waveguide laser, particularly fiber laser

摘要

The invention concerns a multimode waveguide laser (1, 2, 3, 5) which is characterized by the fact that the waveguide's cutoff wavelength is smaller than the smallest wavelength of the emission spectrum of the waveguide laser. Advantageously, the waveguide laser and te diode laser (6) in the wavelength range of the waveguide laser emission are optically decoupled, thus making the diode laser pumped waveguide laser specially suitable for intra-cavity spectroscopy.
