Lumispot Tech, a leading provider of laser pump sources, light sources, and related application systems for special fields, has launched a new high duty cycle, high power, multi-spectral peak semiconductor conduction-cooled stacked array series of LM-8xx-Q1600-F-G8-P0.5-0. This series of laser meets the requirement of miniaturization of lasers for special applications such as unmanned vehicles, laser ranging, LiDAR and many more. 

By expanding the number of spectral lines of the LD, the solid gain medium absorption is stabilized over a wide temperature range, which is conducive to reducing the pressure of the temperature control system, reducing the size and power consumption of the laser, and at the same time ensuring the high energy output of the laser. The product has a high duty cycle and a wide operating temperature range, and can work normally under the condition of 2% duty cycle at 75°C at the highest.

Relying on advanced bare chip testing system, vacuum eutectic bonding, interface material and fusion engineering, transient thermal management and other core technologies, Lumispot Tech can realize precise control of multi-spectral peaks, high working efficiency and advanced thermal management capability to ensure the long term life and high reliability of the array product.
