Patent ID: 7095761

Claim:
A side pumping type Diode Pumped Solid-State (DPSS) laser, comprising: a first laser chip for generating a pumping light; a second laser chip, the second laser chip generating a second pumping light, the second laser chip, although being parallel with the first laser chip, slightly slanted to a predetermined degree so as to avoid a contact between the pumping light and the second pumping light; a first and second focusing lens for focusing the pumping lights; and a side pumping medium for forming the focused pumping lights in a beam mode so as to output as a lasing light, wherein the side pumping medium comprises: a laser material manufactured in a plate type; partial reflection (PR) coating formed on a front surface of the side pumping medium for transmitting a part of the lasing light; and a stop coating formed between the PR coating and the laser material for filtering the pumping lights, and a middle portion thereof being removed for filtering all lights except a light in a pumping light lasing mode.
