Title 01
Title 01
Compact, low-cost system cooling which is integrated into the laser platform. Intelligently controlled to maintain stable wavelength output and intensity.
External fiber coupling options available to achieve easier integration. Multimode fibers typically achieve > 95% efficiency, for single-mode fibers it is > 70%.
Flexible and easy output power adjustment to conserve system lifetime.
-
AOM configuration to achieve up to 200 kHz modulation on the output intensity.
