Ultra Lower Power Green Laser Module Solution

Why Green Laser become popular?  Surely because of the visibility! Green Laser has 8 times luminosity efficiency higher than Red Laser! Luminosity

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 ...

Raytac is excited to announce the new green laser module has recorded the ultra low power achievement. With years on working in digital, high frequency, and opto-electroinc device developments, Raytac has accumulated comprehensive knowledge and experience to create a cutting edge improvement in green laser field.The green laser module employs Osram direct green laser diode, benefits from Rayta'c hardware and firmware effort providing a high stability, ultra low power consumption green laser module performance. The laser pointer equipped Raytac's Class II green laser module has recorded >100hrs battery life time Raytac's latest launched green laser modules encompasses a wide rage of technologies addressing a number of different motivations. The module incorporated a pulsed laser operation at a fixed repetition rate and a wide range of operation temperature between -20 °C ~60 °C. The enrichment has dramatically improved the user scenario in commercial and ...

Mostly, the laser module production base in in China which has raised customers concern involved in trade conflict between US and China. We here would like to announced that All Raytac's laser module is Made In Taiwan, which can help customers escape the trade war risk.

Laser safety is critical to protect consumers from injury and harm when using. Thus, countries have set up different standards such FDA for USA; CE for EU; PSC for Japan. Within these regulation, Japanese PSC is the most discreet. Not only product itself need to comply with the regulation, but also manufacturer and a Japanese domestic importer need to be managed by country. According to the Japanese testing Lab "JQA" "Portable laser devices which emit laser light (limited to visible light) or which are designed to display letters or images are "special specified products". Products like laser pointers and laser thermometers are included in this scope." General speaking, a qualified laser product need to follow below spec and steps to apply PSC mark Design Stage 1. Design the laser product under Class II regulation.(JIS C6802 2011 regulation) 2. Circuit must be APC circuit 3. Whenever single fault happe...
