40W 1270nm Fiber Coupled Laser Diode For Medical
Description
- The 1270nm fiber-coupled diode laser has a core diameter of 600um, a numerical aperture (NA) of 0.39, an SMA905 connection, and a fiber length of more than 1 meter.
- Due to the distributed arrangement of the diodes, the laser module combines high power output with efficient thermal management.
- The laser module supports both air- and water-cooled configurations, ensuring reliability and adaptability.
- This ultra-compact, stand-alone assembly is RoHS compliant and can be ordered with a variety of collimated optics for easy integration into systems.Our highly integrated electronic controls are fully contained within the laser module, eliminating the need for a separate control box. A DC power supply is required to operate the laser.
