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 808 nm wavelength matches the absorption peak of Nd:YAG and similar solid-state crystals precisely, making it widely used in high-power laser pumping, industrial materials processing and medical aesthetic systems.

02 / Core application scenarios

Core application scenarios

01
Industrial laser pumpingPump sources for diode-pumped solid-state lasers (DPSSL) and fiber lasers, and for optical parametric oscillators (OPO).
02
Industrial materials processingFine plastic and metal welding, surface heat treatment, laser cladding and cutting.
03
Medical aesthetic equipment808 nm painless hair-removal systems, dermatological treatment and infrared therapy equipment.

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 150 μm emitting width gives an even spot, easing downstream micro-optic collimation and system coupling.
03
Efficient conversionA slope efficiency of 1.3 W/A delivers 50 W QCW output at 50 A drive, 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.
