Raman Amplification And Pulsed Lasing In Cladding-Pumped Germanosilicate Fiber
Introduction: Cladding-pumped rare-earth-doped fibers and Raman fiber devices have been two of the most compelling advances in the area of fiber amplifiers and lasers in recent years. Both cladding-pumped fibers and Raman fiber devices are primarily high-power devices. Cladding-pumping enables pumping with multi-mode pump sources that deliver high-power at a low cost. The core of the double-cla...
متن کاملSide-pumped crystalline Raman laser.
A crystalline Raman laser is pumped at 90° to the Raman laser axis by a single pass from a line-focused 532 nm pump laser of pulse duration 10 ns. The Raman laser threshold was 6.1 mJ, and at 12 mJ pump energy, a maximum output energy of 2.7 mJ was obtained with a slope efficiency of 46%. The threshold pump intensity is within a factor of 2 of the same device when end-pumped. The results highli...

Pulsed laser deposition (PLD) is a versatile technique for the fabrication of nanostructures due to the possibilities it offers to control size and shape of nanostructured deposits by varying the laser
متن کاملFemtosecond laser ablation of ZnO nanorods for two-photon-pumped random lasing and optical data storage
Femtosecond laser ablation based on two-photon absorption was employed to cut ZnO nanorods into uniform ZnO nanoparticles of deep subwavelength size. The fabricated ZnO nanoparticles possess a shorter mean transport length for photons at the emission wavelength and a much smaller scattering cross section at the pump wavelength, leading to highly efficient two-photon-pumped random lasing with a ...
متن کاملElectrically pumped waveguide lasing from ZnO nanowires.
Ultraviolet semiconductor lasers are widely used for applications in photonics, information storage, biology and medical therapeutics. Although the performance of gallium nitride ultraviolet lasers has improved significantly over the past decade, demand for lower costs, higher powers and shorter wavelengths has motivated interest in zinc oxide (ZnO), which has a wide direct bandgap and a large ...
