The Paladin Compact 355-4000 solid-state, ultraviolet (UV) laser from Coherent delivers 4 Watts of quasi-CW output at 355 nm in a small footprint package. This laser is specifically designed for OEMs, due to its combination of low cost-of-ownership, small size, high-quality output, and operational simplicity. It can be either air-cooled or water-cooled, offering system builders enhanced flexibility. Additionally, its beam parameters are identical to the larger-sized 4 Watt Paladin model, making it easier to use with existing optical designs. The laser requires only a single, long-lived pump diode rather than two pump diodes.
