01 / Product introduction

Product introduction

This 808 nm high-power laser bar uses advanced quantum-well epitaxial growth with an optimised conduction-cooled package. The 300 W variant is the highest-power bar in the family, packing 62 emitters at a 66% fill factor to reach 300 W of quasi-continuous output at 250 A drive. It targets the most demanding high-power pumping and industrial processing applications where energy density is the limiting factor.

03 / Core advantages

Core advantages

01
Highest power in the family62 emitters at 66% fill factor deliver 300 W QCW output, the highest energy density in the 808 nm bar range.
02
Efficient heat removal, high reliabilityA conduction-cooled structure with hard-solder eutectic bonding gives low thermal resistance and strong thermal-shock tolerance at high drive currents.
03
Controlled beam at high powerDivergence of 36° fast axis and 9° slow axis with a 100 μm emitting width keeps the spot even despite the raised output.
04
In-house IDM productionA fully self-controlled III-V compound semiconductor platform allows cavity length, emitter count and fill factor to be customised to requirement.
