Laser device for video display application, has oscillator including optical fiber whose chromatic dispersion is adjusted to obtain phase matching, and pump source for emitting pump wave with power greater than/equal to specific Watts

摘要

The device has an infrared laser pump source (1) for emitting a pump wave in a continuous manner, with power greater than or equal to 5 Watts. An optical fiber parametric oscillator has a non linear optical fiber (4) e.g. photonic crystal fiber or polarization maintaining fiber, whose chromatic dispersion is adjusted so as to obtain a phase matching. A demultiplexing device (7) is arranged in downstream of the oscillator to separate a stokes wave, an anti-stokes wave and a part of the pump wave. The laser pump source comprises diode pumped neodymium-doped yttrium aluminum garnet laser, diode pumped Ytterbium-doped yttrium aluminum garnet laser or diode pumped ytterbium doped fiber laser.
