The nanosecond solid-state laser series utilizes semiconductor side-pumping technology, featuring high peak power, high repetition rate, high-quality flat-top beam, long lifespan, low thermal effect, compact structure, and easy maintenance. Among them, the three standard models NS50, NS300, and NS600, at a repetition rate of 100 Hz, can achieve single-pulse energies of 50 mJ, 300 mJ, and 600 mJ at 1064 nm, corresponding to 25 mJ, 120 mJ, and 240 mJ at 532 nm, and 15 mJ, 100 mJ, and 200 mJ at 355 nm, with a pulse width of 8-10 ns, divergence angle ≤1 mrad, energy stability at 1064 nm <0.7%, and jitter ≤2 ns. The two OPO models, NS-OPO-355 and NS-OPO-532, operate at a repetition rate of 50 Hz with a pulse width of 5-10 ns, offering pump options at 355 nm and 532 nm respectively, enabling wideband tunable output (420-2300 nm). The entire series can meet the demands of industrial processing, atmospheric detection, and scientific research applications. By leveraging higher electro-optical conversion efficiency and lower thermal effects, while ensuring output beam quality and power, it significantly reduces equipment energy consumption and maintenance costs.
