چکیده
The generation of a 33.7 W radially polarized output is demonstrated by way double-pass amplification in Ho:YAG thin-slab crystal. amplifier system was seeded with the beam from continuous-wave 13.2 W, 2.1 µm rod laser, which exploited gain medium bifocusing and ring-shaped pump spot to promote preferential lasing on Laguerre–Gaussian mode. By compensating for both thermally induced stress birefringence crystal Gouy phase shift resulting astigmatic focusing seed, only marginal degradation observed across 95 range power into amplifier.

Efficient radially polarized laser beam generation with a double interferometer.
Conversion of a linearly polarized CO(2) laser beam into a radially polarized beam is demonstrated with a novel double-interferometer system. The first Mach-Zehnder interferometer converts the linearly polarized input beam into two beams with sin(2) θ and cos(2) θ intensity profiles, where θ is the azimuthal angle. This is accomplished by using two spiral-phase-delay plates with opposite handed...
متن کاملPolarized thermal emission by thin metal wires
We report new measurements of the linear polarization of thermal radiation emitted by incandescent thin tungsten wires, with thicknesses ranging from five to hundred microns. Our data show very good agreement with theoretical predictions, based on Drude-type fits to measured optical properties of tungsten. Polarized thermal emission by thin metal wires 2
متن کاملDiffraction-limited polarized emission from a multimode ytterbium fiber amplifier after a nonlinear beam converter.
The multimode and depolarized output beam of a highly multimode diode-pumped Yb-doped fiber amplifier is converted to a diffraction-limited, linearly polarized beam by a self-referencing two-wave-mixing process in an infrared-sensitive photorefractive crystal (Rh:BaTiO3). As much as 11.6 W of single-mode output is achieved with a 78% multimode-to-single-mode photorefractive conversion efficiency.
متن کاملTunable gain-clamped double-pass Erbium-doped fiber amplifier.
A tunable, gain-clamped (GC) double-pass Erbium-doped fiber amplifier (EDFA) with a linear laser-cavity configuration has been demonstrated. It solves the problems existing in the conventional linear-cavity GC-EDFA based on two fiber Bragg gratings (FBGs), in which the clamped-gain is very difficult to be tuned. In the new GC-EDFA, the lasing oscillation for clamping the gain is produced in a l...
متن کاملFiber optical parametric amplifier with double-pass pump configuration.
Characteristics of fiber optical parametric amplifier (FOPA) with double-pass pump configuration are experimentally investigated. The double-pass pump FOPA exhibits more than two-fold steeper gain slope in comparison to the conventional FOPA due to elongation of effective fiber length. In the L-band amplification band, a secondary idler is generated and used as the transmission signal in lieu o...
