Energy enhancement of Nd,Sc:YAG crystal in passively Q-switched lasers
Listed in ScienceDB
We report on the laser performance of Nd,Sc:YAG for the first time. In this study, 10 at.% Sc3+ ions were doped into Nd:YAG crystal to form Nd,Sc:YAG crystal, which improves the saturation flux while nearly maintaining the excellent properties of Nd:YAG crystal.
Description
The continuous-wave (CW) and passively Q-switched (PQS) laser performances of Nd,Sc:YAG crystal at 1064 nm were investigated. The CW output power reached 4.5 W at the absorbed pump power of 8.07 W with a slope efficiency of 63.1% and optical-to-optical efficiency of 55.7%.
A stable PQS laser was achieved employing Cr4+:YAG as a saturable absorber (SA). The maximum average output power attained was 1.84 W with a slope of 23.5%. The pulse width, pulse energy, and frequency were 17.0 ns, 69.2 µJ, and 26.6 kHz, respectively. Compared to the Nd:YAG crystal, the pulse energy for the Nd,Sc:YAG crystal was enhanced by approximately 1.7 times. These results show that Nd,Sc:YAG crystal is a promising laser material with larger energy storage capacities, making it suitable for the application of high-energy lasers (HEL) with high repetition rate.
