450nm 445nm Fiber Coupled Blue Lasers 0.8W - 200W Laser Power
450nm, 445nm, Laser Power from 0.8W to 200W 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.
