“…Compared with the active Q-switched pulsed lasers reported in refs. [51] and [52], the pulsed laser using BTW glass free-space AOM as the Q-switched device shows the narrowest pulse width, which shows that the BTW glass free-space AOM has good pulse compression function. In addition, the pulsed laser using the BTW glass free-space AOM as the Q-switched device shows the maximum optical-to-optical conversion efficiency, which further illustrates that the energy loss of the BTW glass free-space AOM with high diffraction efficiency is very small.…”

The Q‐switched material and device have attracted extensive attention due to their irreplaceable role in pulsed lasers. In this paper, BaO‐TeO2‐WO3 glass (BTW glass) with sound velocity and sound attenuation coefficient of 3422 m −1s and 0.653 dB/cm is successfully selected and fabricated as acousto‐optic material. Both free‐spaced and fiber‐coupled acousto‐optic modulation devices based on BTW glass are designed and fabricated. The primary parameters such as diffraction efficiency, polarization extinction ratio, and insertion loss are comparable to or even surpassed that of commercial devices. A 1064 nm pulsed laser is successfully realized with a BTW glass free‐spaced acousto‐optic modulator. The maximum optical conversion efficiency, the narrowest pulse width, and the maximum single pulse energy of the 1064 nm pulsed laser are 32%, 54 ns, and 242.6 μJ, respectively. Both the device and laser performance indicate that the BTW glass is a remarkable acousto‐optic material.This article is protected by copyright. All rights reserved

“…In 2016, Lin et al reported a passively Q-switched Nd:YAG laser operated at 1319 and 1338 nm laser under directly pumping at 885 nm, and the maximum total output energy was 55 µJ with a maximum repetition rate of 64.10 kHz [13]. Recently, Wu et al studied the Q-switched 1319 and 1338 nm dual-wavelength operation of an LD, end-pumped, composite Nd:YAG laser, and a maximum output energy of 260 µJ was obtained at a repetition frequency of 20 kHz [14].…”

We demonstrate a high-energy dual-wavelength Nd:YAG solid-state laser emitting at 1.3 μm. To scale up the laser output power and beam quality, the resonator has a two-rod configuration side-pumped by a quasi-continuous wave, pulsed laser diode instead of a continuous wave format, so as to mitigate the thermal effect in the laser crystal effectively. Two acousto-optic Q-switches are adopted to obtain higher peak power. By precise coating on the cavity mirrors, simultaneous oscillation at 1319 and 1338 nm is achieved with the intension ratio of near 59:50. The oscillator operates at a repetition frequency of 400 Hz and pulse duration of 117 ns, delivering a maximum average output power of 49.4 W with an optical-to-optical conversion efficiency of 12%. The calculated peak power and pulse energy are up to 1.06 MW and 123.5 mJ, respectively, which is, to our best knowledge, the highest energy Nd:YAG laser in the 1.3 μm region.

“…In recent years, many works are investigated to achieve various kinds of dual-wavelength output. Up to now, various dual-wavelength oscillations of Nd:YAG crystal have been achieved in different systems, such as, 1357/1444 nm [6], 1116/1123 nm [7], 1319/1338 nm [8,9], 1074/1112 nm [10], 946/1064 nm [11,12], 1319/1356 nm [13], etc. Recently, it has been found that the Nd:YAG laser can be operated at cryogenic temperatures to obtain the dual-wavelength emissions at 1061 and 1064 nm [14,15].…”

A diode-end-pumped cryogenically cooled Nd:YAG laser is demonstrated with dual-wavelengths at 946 nm and 1061 nm. As temperature varies from 300 K to 190 K, a transition occur from single-wavelength at 946 nm to dual-wavelength at 946 nm and 1061 nm. Only the line at 1061 nm oscillated for the temperature less than 180 K. Moreover, a theoretical simulation of oscillation condition at cryogenic temperatures is implemented, leading a deep insight into the physical mechanism of dual-wavelength generation.
