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

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.
