STN Series High Power 450nm Blue Lasers

1. STN Series Fiber Coupled Blue Lasers

High brightness, fiber delivered blue lasers for metals processing

 

The STN Series Fiber Coupled Blue Lasers are high brightness blue lasers that process metals better and more efficiently than IR or green lasers and integrate with standard scanning systems. This enables them to service a wide range of welding, additive manufacturing, and other materials processing applications in batteries, e-mobility and consumer electronics. This series combined with scan head delivery, offers an ideal laser for metal processing due to the high absorption of blue light by metals: including 13x for copper and 3x for aluminum. Reducing the excess heat input compared to infrared lasers enables spatter-free and defect free welds with the highest possible mechanical and electrical performance. With available output powers from 125W to 1kW, these blue lasers can power mass production solutions for <1mm copper and aluminum welds which require a large process window and demand extremely high yields.

 

Key Benefits

  • High quality low to spatter-free welding

  • Dramatically improves process performance and process window

  • Enables welding processes not possible or with low yields with IR

 

Application

  • Batteries and energy storage

  • E-mobility

  • Consumer electronics

  • Interconnects

  • Electronics packaging

  • 3D metal printing (powder bed fusion and wire feed)

Packaging Dimension:

  1. STK Series blue laser consists of up to 4 submodules50W per module. Power can be supplied separately or in series.

  2. STK Series blue laser cooling water inlet and outlet size: Outer 10mm* Inner 6.5mm.The water flow should be at least 5L/min.

  3. *: Optional functions.

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.
