PRODUCT DESCRIPTION
1. ST Series DPSS UV Lasers
Diode end-pumped lasers adopt full sealed-off design with small volume and low power consumption as well as fiber-coupled pumping, which is easily for the integration of system and equipment. The modularized design provides the convenience for changing by customers. The laser beam is TEMoo with high beam quality, high peak power and short pulse width. Excellent resonator design can keep average laser power and pulsed peak power stable & constant. This laser can meet the requirements of most industrial precision processing. The micro-optics design of key pumping source is the most advanced all over the world.
