February 2017 – JGMA has developed a low-cost and compact 355 nm laser for UV-MALDI and similar applications. The laser prototype generates more than 20 uJ of 355 nm pulse energy at pulse rates to 25 kHz (>500 mW average) with cw pumping, and at pulse rates from 100 Hz to 10 kHz with quasi-cw pumping. The laser head should fit into a volume no larger than 1″H x 2″W x 6″L, and possibly smaller. JGMA anticipates an OEM sell price well under $15,000 for blanket-order quantities of 100 or more lasers.
