Portable 532 nm iodine-stabilized DPSS laser for length standard

摘要

A diode-pumped solid-state (DPSS) laser, such as a Nd:YAG green laser, has become smaller in size , lower in cost and higher in performance. Therefore, the DPSS lasers are widely used in many industries. For a laser interferometers and secondly length standards, stable light sources are in demand. We have developed 532 nm iodine-stabilized DPSS lasers used for the applications. The lasers have following features ; compact design (D 280 × W 170× H 120 mm), high power (3 mW), high stability ( < 1 × 10~(-10): allann deviation k=1 at τ =1 sec), and easy operation.
