Why Application Changed from DPSS Green Laser To Direct Green Laser
Recently, green laser application has been moved from DPSS solution to Directed green. Not only becasue of the lower power consumption, but also a safer, wider range of operation temperature and stability concerns. Diode-pumped Solid-State Laser called as DPSS。 In decades, 532nm DPSS green laser has been played an important role for laser application in all fields. However, upon the structure of 532nm green laser, it brought up an inherent problem and concerns limited the applications and usage. Below picture listed some structure of DPSS green laser. 532nm green laser pumps by an 200mW 808nm invisiable laser diode. The laser through KTP and YVO4 to change the wavelength from 808nm to 1064nm and to 532 nm. During the power stepping, KTP and YVO4 are bringing the factor which confilct each other. Therefore, accompany with the temperature changing, KTP and YVO4 may lost the balance and result in the 532nm laser stop working. Furthermore, as the 532nm laser created ...
