Product Description

Product Introduction
This product uses a 444 nm semiconductor laser as the pump source and achieves 261 nm ultraviolet continuous-wave laser output through direct combination with laser crystals and nonlinear frequency doubling technology. It features a simple design, single longitudinal mode, and compact size. Compared to traditional 266 nm CW lasers, it offers higher energy density and a smaller focused spot, enabling greater optical resolution and higher processing precision.
