Portable 532 nm Iodine-Stabilized DPSS Laser for Length Standard
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.
