1:Precise Wavelength Stabilization:
Built-in wavelength stabilization technology ensures a highly stable output at 808 nm.
Effectively minimizes wavelength drift caused by temperature fluctuations and current variations.
Guarantees excellent spectral consistency, essential for solid-state laser pumping, medical devices, and precision industrial systems.
2:Linear Beam Profile (Line-Shaped Spot):
Special optical design delivers a uniform line-shaped beam, making it ideal for applications such as:
Laser hair removal and dermatology treatments - uniform energy distribution for safer and more effective treatments.
Plastic welding & industrial processing - consistent heating along the processing line.
Solid-state laser pumping - improved coupling efficiency with gain media.
