Gain boost with synchronized multiple wavelength pumping in a solid-state laser |
摘要 |
A solid-state eye-safe laser and method with gain boost by dual-wavelength, synchronized pumplights. The laser includes a medium doped with ions that emit light at a laser wavelength as a result of the transition of electron energy from an upper energy level manifold to a lower energy level manifold. A first pumplight couples energy into the medium at a first wavelength that excites a first portion of the ions into said upper energy level manifold. A second pumplight couples energy into said medium at a second wavelength that excites a second portion of the ions to a third energy level manifold. A fraction of the ions relax to the upper energy level manifold and thereby increase the gain of the laser (2). The laser may be an erbium crystal laser, using yttrium-aluminum-garnet operating near 1640 nanometers. A second ion, such as ytterbium, may be diffused into the lasing medium, and an inter-ionic energy transfer employed to coupled the second pumplight energy to the upper level energy manifold of he laser transition.
