01 / Product introduction

Product introduction

This 1940 nm 10 W laser bar uses advanced semiconductor quantum-well epitaxy with a conduction-cooled package, giving high absorption efficiency, excellent stability and high reliability. At 1940 nm it matches the strong absorption peak of the water molecule precisely, making it a competitive core source for minimally invasive and non-invasive aesthetic procedures and polymer materials processing.

Core application scenarios

01
Laser medicine and aestheticsNon-invasive and minimally invasive dermatological treatment devices, superficial resurfacing and brightening, and fine surgical procedures.
02
Industrial and specialty materials processingWelding of high-absorption transparent and white plastics, and precision cutting and heat treatment of polymer materials.
03
Laser pumping and researchPump sources for 2 μm-band solid-state and fiber lasers such as thulium- and holmium-doped systems.

03 / Core advantages

Core advantages

01
Prime absorption bandPrecisely aligned to the water-molecule absorption peak, giving very high photothermal conversion efficiency and a precisely controlled thermal-damage zone in medical and materials work.
02
Reliable conduction coolingA high-thermal-conductivity heat sink with an optimised package provides excellent thermal management and long service life at 45 A drive.
03
Precise beam control, easy coupling19 emitters at a 30% fill factor with a 150 μm emitting window give excellent beam quality, greatly simplifying micro-optic shaping and coupling.
04
In-house IDM productionA fully self-controlled semiconductor line gives consistent quality and supports multiple power levels and deep module customisation.
