Laser diode pumped Nd:YVO4 laser.

The Review of Laser Engineering, 1990
Having a larger stimulated emission cross section and stronger fluorescence emission, a laserdiode (LD) pumped Nd: YVO4 laser has higher efficiency and power than Nd: YAG laser.Spectral property and CW end-pumped lasing characteristics have been measured on thismaterial.

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 ...

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Quantifying Subsurface Weak in‐Plane Magnetization of Mixed Phase BiFeO3 by Scanning Nitrogen Vacancy Magnetometry

Advanced Functional Materials, EarlyView.
We use scanning nitrogen vacancy magnetometry to directly image the weak in‐plane magnetic moments in mixed phase BiFeO3 at the nanoscale and quantify the local magnetic moments to be 18.8±2.0 μB/nm2 in the rhombohedral‐like phase and 1.5±0.6 μB/nm2 in the well‐known non‐magnetic tetragonal‐like phase.

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.,).
