• RS232 interface

Melles Griot first began manufacturing DPSS lasers in 1999. These devices provide compact and reliable sources of laser light with minimal heat generation and maximum resistance to mechanical shock and vibration.

Standard DPSS Laser Systems from Melles Griot provide excellent output power and pointing stability from a compact laser head. This is achieved through state-of-the art thermal management and current control, which improves performance and reliability in harsh environments.

Fiber Optic Beam Delivery is available for most products, in addition to free-space beam delivery. With fiber core sizes of approximately 4 microns, maintaining alignment, and the resulting power efficiency and stability can be challenging. Melles Griot addresses this by incorporating the fiber launch components inside the laser head, and maintaining them at the same temperature as the laser itself. The result is stable power and efficient coupling; over time, over temperature, and during mechanical shock and vibration.
