Transient Analysis of Pump-induced Lensing Effects in Alexandrite Lasers Using Pump-Probe Technique [PDF]

EPJ Web of Conferences
A novel transient pump-probe method is used to differentiate thermal and population pump-induced lensing mechanisms. In diode-pumped Alexandrite lasers, excellent agreement is found between theory and experiment and the population lens is found to be ...

Directly diode-pumped, Kerr-lens mode-locked, few-cycle Cr:ZnSe oscillator

, 2019
Lasers based on Cr$^{2+}$-doped II-VI material, often known as the Ti:Sapphire of the mid-infrared, can directly provide few-cycle pulses with super-octave-spanning spectra, and serve as efficient drivers for generating broadband mid-infrared radiation ...

Effect of Pump Beam Shape on Thermal and Stress Distribution within the Laser Crystal in Diode Pumped Solid-State Lasers

Syrian Journal for Science and Innovation
Thermal effects formed in a solid-state laser crystal, which cause the appearance of thermal lensing، mechanical stress and birefringence, lead to laser beam distortion and shorten the lifetime of laser crystal، and hinder getting a high-quality laser ...

5 kW Near-Diffraction-Limited and 8 kW High-Brightness Monolithic Continuous Wave Fiber Lasers Directly Pumped by Laser Diodes

IEEE Photonics Journal, 2017
Tandem pumping technique are traditionally adopted to develop >3-kW continuous-wave (cw) Yb3+-doped fiber lasers, which are usually pumped by other fiber lasers at shorter wavelengths (1018 nm e.g.,).

Investigation on efficiency declines due to spectral overlap between LDAs pump and laser medium in high power double face pumped slab laser

Results in Physics, 2018
In high power diode lasers, the input cooling water temperature would affect both output power and output spectrum. In double face pumped slab laser, the spectrum of two laser diode arrays (LDAs) must be optimized for efficiency reason.

Eye-Safe Solid-State Quasi-CW Raman Laser with Millisecond Pulse Duration

, 2012
We demonstrate the first quasi-CW (ms-long pulses, pump duty cycle of 10%) end-diode pumped solid state laser generating eye-safe radiation via intracavity Raman conversion. The output power at the first Stokes wavelength (1524 nm) was 250 mW.

Femtosecond pulses at 50-W average power from an Yb:YAG planar waveguide amplifier seeded by an Yb:KYW oscillator [PDF]

, 2012
We report the demonstration of a high-power single-side-pumped Yb:YAG planar waveguide amplifier seeded by an Yb:KYW femtosecond laser. Five passes through the amplifier yielded 700-fs pulses with average powers of 50 W at 1030 nm. A numerical simulation
