STK Series Fiber Coupled Laser Diodes (<500W)

Our STK series fiber-coupled laser diodes can be pided into two categories: single emitter laser diodes and multi-single emitter laser diodes.

1. Single Emitter Laser Diodes

Single emitter laser diodes can provide multi-wavelength covering 405nm to 976nm, output power from 2mW to 10W. Mainly used in the area of fiber laser pumping ,computer to plate(CTP), DPSS laser pumping, medical use, aiming beam, industry etc. For different application, varieties of packages with optional functions of aiming beam, photo detector, TEC, fiber detector, thermistor and other functions are available.

2. Multi-single Emitter Laser Diodes

Multiple single emitter laser diodes build upon the foundation of multi-emitter coupling technology, to obtain high power and high brightness diode laser. Varieties of packages with optional functions of aiming beam, photo detector, TEC, fiber detector, thermistor and other functions are available. Multi single emitter laser diodes have great advantages in high reliability and high performance. In multi-single emitter laser diodes, we have patented many improved optical designs. And these compact packages and commercially recognized formats allow easy integration into the existing products. Multi single emitter diode lasers include wavelengths from 635nm-1064nm, output power from 1.6W-500W.

Applications:

Medical use

Our High Power Diode Laser Modules are manufactured by adopting specialized fiber-coupling techniques, resulting in volume products with a high efficiency, stability and superior beam quality. The products are achieved by transforming the asymmetric radiation from the laser diode chip into an output fiber with small core diameter by using special micro optics. Inspecting and burn-in procedures in every aspect come to a result to guarantee each product with the reliability, stability and long lifetime.

Our research staffs are constantly improving and innovating the processing technology in the producing process, based on the professional knowledge and experience accumulated in long-terms. We are also continuously developing new products to meet customers’ specific needs.

To provide high quality products with reasonable price is our always goal.

OPERATING NOTES

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 35℃.
Storage temperature ranges from -20℃ to +70℃.
