RealLight offers three versions of diode stack: GS1 series vertical diode laser stack, GS2 series vertical diode laser stack and GS3 series horizontal diode laser stack. Utilizing the high reliable AuSn solder technology and low thermal resistance package, these multi-bar modules provide large duty cycle and high peak power output under QCW operation. GS1 series and GS2 series contain up to 5 diode bars, and the stacked diode laser arrays deliver a high peak power output of one thousand watts. Custom solution with combining 2-10 stacks is available for GS2 series. GS3 series features compact design by stacking up to 12 diode bars, with peak power up to 1200W. Multiple-wavelength stacks with output wavelengths near 808nm for GS2 series and GS3 series are available upon request, which allow pumping at a wide operating temperature. And 940nm output wavelength is customizable for all product lines. The diode stacks are preferred for applications include pumping, material processing, laser illumination, aesthetic treatment and scientific research.
