Abstract:
1. A pumplight driven solid-state eye-safe laser, comprising: a first lasing medium operable to lase energy at a first wavelength; a second lasing medium coupled with said first lasing medium and defining a first resonant cavity for reflectively retaining said first wavelength energy therein, said second lasing medium operable to lase energy at a second wavelength within the eye-safe band of wavelengths; a transmissive/reflective layer disposed along a coupling between said first lasing medium and said second lasing medium, said layer being transmissive at said first wavelength and reflective at said second wavelength, thereby defining a second cavity for reflectively retaining said second wavelength within said second lasing medium; and an output coupler disposed at an end of said second lasing medium opposite said transmissive/reflective layer.
