Direct generation of a first-Stokes vortex laser beam from a self-Raman laser.

چکیده
We demonstrate the direct generation of a first-order LG(01) Laguerre Gaussian (vortex) mode operating at the first-Stokes wavelength of a diode end-pumped, Nd:GdVO(4) self-Raman laser. To the best of our knowledge, this is the first report of intracavity stimulated Raman scattering (SRS) being used as a method for frequency conversion of a vortex laser beam and it is effective in enabling the frequency-converted (Stokes) beam to have the same LG(01) mode as the fundamental beam.

متن کاملUse of a Two-Channel Moiré Wavefront Sensor for Measuring Topological Charge Sign of the Vortex Beam and Investigation of Its Change Due to an Odd Number of Reflections
One of the solutions of the Helmholtz equation is the vortex beams. In the recent decades, production and applications of these types of beams have found serious attentions. Determination of the vortex beam topological charge and its sign are very important issues. Odd number of reflections of the vortex beam changes its vorticity. In this paper, we have used a q-plate to generate a vortex beam...
متن کاملChirped-pulse Raman amplification for two-color, high-intensity laser experiments
We report generation of millijoule-level Stokes (873, 961 nm) and anti-Stokes (738, 685, 639 nm) sidebands of 800 nm terawatt pulses by inserting a multistage Ba NO3 2 Raman shifter-amplifier into a conventional Ti:sapphire chirped-pulse amplification system. The Raman subsystem requires no additional pump lasers and does not compromise the energy, duration, or beam quality of the main 800 nm p...
متن کاملHigh-Power, Solid-State, Deep Ultraviolet Laser Generation
At present, deep ultraviolet (DUV) lasers at the wavelength of fourth harmonics of 1 μm (266 nm/258 nm) and at the wavelength of 193 nm are widely utilized in science and industry. We review the generation of these DUV lasers by nonlinear frequency conversion processes using solid-state/fiber lasers as the fundamental frequency. A DUV laser at 258 nm by fourth harmonics generation (FHG) could a...
