01 / Product introduction

Product introduction

This 808 nm high-power laser bar uses advanced quantum-well epitaxial growth with an optimised conduction-cooled package, delivering high optical output, very high electro-optical conversion efficiency, excellent temperature stability and long service life. The 100 W variant widens the array to 47 emitters at 50% fill factor, matching the absorption peak of Nd:YAG and similar crystals for high-power pumping, industrial materials processing and medical aesthetic systems.

02 / Core application scenarios

Core application scenarios

03 / Core advantages

Core advantages

01
Efficient heat removal, high reliabilityA conduction-cooled structure with hard-solder eutectic bonding gives low thermal resistance, strong thermal-shock tolerance and long operating life.
02
Precise beam controlOptimised divergence of 35° fast axis and 8° slow axis with a 100 μm emitting width gives an even spot, easing downstream micro-optic collimation and system coupling.
03
Scaled optical output100 W QCW output at 100 A drive from a 47-emitter array, with spectral width held to 3 nm.
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.
