Abstract

A new disordered crystal Nd:SrAl₁₂O₁₉ (Nd:SRA) with an Nd³⁺ doping concentration of 5% was successfully grown using the Czochralski method. A diode-pumped Nd:SRA Q-switched laser operating at 1049 nm was demonstrated for the first time, to the best of our knowledge. Based on an MXene Ti₃C₂T_x sheet, a high repetition rate of 201 kHz and a Q-switched pulse width of 346 ns were obtained when the absorbed pump power was 2.8 W. The peak power and single pulse energy were 1.87 W and 0.65 μJ, respectively.
