Intra-Cavity Raman Laser Operating at 1193 nm Based on Graded-Index Fiber

589 nm Light Source Based on Raman Fiber Laser

Harmonic generation using nonlinear optical crystals is currently the most efficient approach of obtaining visible and ultraviolet lasers. Diode-pumped Nd-doped solid-state lasers can operate in the blue, green, and red spectral regions by intracavity frequency doubling. However, there are few solid-state laser sources that can efficiently produce laser emission in a region covering 550 to 650 ...

Phase-conjugate fluorozirconate fiber laser operating at 800 nm.

We report phase-conjugate feedback into a fluorozirconate optical fiber amplifier at infrared wavelengths. By using a semiconductor laser diode at 807 nm, a grating is established in photorefractive BaTiO(3) that, in the ring configuration, provides feedback into the amplifier necessary for laser action. Once written, the grating is self-sustaining, and lasing is observed even after the laser d...

Three-cascaded 1407-nm Raman laser based on phosphorus-doped silica fiber.

We report a laser-diode-pumped 1407-nm Raman fiber laser with an output power of 1 W. In this three-cascaded cw Raman laser, based on a single active phosphorus-doped silica fiber, for the first time to the authors' knowledge successive generation of Stokes components of essentially different frequency shifts (1330 and 490cm(-1)) has been realized. These Stokes components are associated with bo...

Visible supercontinuum generation in a graded index multimode fiber pumped at 1064  nm.

We observe efficient supercontinuum generation that extends into the visible spectral range by pumping a low differential mode group delay graded index multimode fiber in the normal dispersion regime. For a 28.5 m long fiber, the generated spectrum spans more than two octaves, starting from below 450 nm and extending beyond 2400 nm. The main nonlinear mechanisms contributing to the visible spec...
