1. STNU Series High Power Blue Lasers

We are pleased to offer the world’s first revolutionary high-power blue laser for industrial welding and cutting applications. Based on our patented proprietary technology, the blue laser enables processing speed from 2x to over 10x current infrared lasers (1um) for a large range of metal processing applications. Benefits of high power blue lasers are:

Advantages of Blue Laser Processing:

IR lasers have always had difficulty welding copper due to low absorptivity (~5%) (need high peak power) and high thermal diffusivity. As a result, IR lasers can only operate in keyhole mode generating and there are following limits:

Absorption Is Everything 

Blue laser has superior efficiency. Physics dictates the efficiency of energy absorption. Compared to industry-standard IR wavelength, blue absorption is 3-20x better and blue laser enable process speed gains of 2-10x.

2. STK Series Fiber-coupled Blue Lasers

The STK series fiber-coupled blue lasers are manufactured by adopting specialized fiber-coupling techniques, resulting in high efficiency, stability and superior beam quality. The asymmetric radiation from the laser diode chips are coupled into an output fiber with small core diameter by using special micro optics. Their prices are reasonable and cheaper in the market.
