450nm Blue Lasers

STK Series Blue Diode Lasers

1.500W-2000W Blue Diode Lasers

Compared with traditional laser products, our blue diode laser has a higher absorption rate for materials such as copper and aluminium, and can process non-ferrous metals with lower power. Our blue laser is more compact and easier to use. With flexible laser output mode, it can be integrated into the processing system conveniently.

Our blue lasers can be used in wide applications like welding, cladding, surface treatment, lithium-ion battery manufacturing, etc. Our professional laser application team, with good knowledge and experience, provides the best laser system solution for our customers all around the world.

Features:

• Good beam quality

• High electro-optical conversion efficiency

• Excellent power stability

• Two operation modes: CW and modulation

• Excellent system reliability

• Max modulation frequency up to 5kHz

• Easy-to-use control interface

Operating Notes

Applications:

• Avoid eye and skin exposure to direct radiation during operation.

• ESD precautions must be taken during storage, transportation and operation.

• Short circuit is required between pins during storage and transportation.

• Please connect pins to wires by solder instead of using socket when operation current is higher than 6A. Soldering point should be close to the root of the pins. Soldering temperature should be lower than 260 and time shorter than 10 second.

• Make sure the fiber output end is properly cleaned before operation of laser. Follow safety protocols to avoid injury when handling and cutting the fiber.

• Use constant current power supply to avoid surge current during operation.

• Laser diode must be used according to the specifications.

• Laser diode must work with good cooling.

• Operation temperature ranges from 15 to 30℃

• Storage temperature ranges from -20 to +70℃

3.   <100W 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.
