Pulsed LD side-pumped MgO: LN electro-optic cavity-dumped 1123 nm Nd: YAG laser with short pulse width and high peak power

Abstract

We report a cavity-dumped 1123 nm laser with narrow pulse width and high peak power by an MgO: LN crystal electro-optic (EO) modulator. Based on the structural optimization design of a folded biconcave cavity using the 808 nm pulsed laser diode (LD) side-pumped ceramic Nd: YAG rod, output pulses with maximum pulse energy and peak power up to 39.6 mJ and 9.73 MW were obtained, corresponding to 100 Hz repetition rate and 4.07 ns pulse width. The instabilities of pulse width and pulse energy were $\pm$1.55% and $\pm$2.06%, respectively. At the highest repetition rate of 1 kHz, the pulse energy, pulse width, and peak power were 11.3 mJ, 5.05 ns, and 2.24 MW, respectively. The instabilities of pulse width and pulse energy were $\pm$2.65% and $\pm$3.47%, respectively.

High stability and low noise laser-diode end-pumped Nd: YAG ceramic passively Q-switched laser at 1123 nm based on a Ti3C2T x -PVA saturable absorber

“…6(b), red curve). The power instability ρ and the noise Γ L-RMS of the passively Q-switched pulsed laser at the maximum average power were measured to be ±5.23% and 5.21% within a 4 h period using the following equations: [30,31]…”

Effect of laser remelting on microstructure and properties of two Ni-base coatings by supersonic particles deposition

“…The specific process parameters for the preparation of coating were shown in table 3. The Ni-based alloy coating prepared by supersonic particle deposition was remelted by the ZKSX1000 continuous type laser cladding system, because the pulse laser may cause deep damage to the material surface [30][31][32][33]. Argon was used as protective…”

On fast LuAG:Ce scintillation ceramics with Ca2+ co‐dopants

“…In comparison, the lower growth temperature and shorter growth period of its ceramic counterpart could greatly reduce both AD production in the lattice and manufacture costs. Moreover it is much easier to achieve uniform ion co‐doping in LuAG:Ce ceramic 12,13 . In addition, Chen Hu et al recently reported LuAG:Ce ceramic to have excellent radiation damage resistance, making it a very attractive material for HEP experiments 14 …”
