Laser Diodes

  • Update:Aug 07, 2020
  • View:

We have been specializing in design, development and manufacturing of high power laser diodes from 905 to 1800 nm wavelengths using MOCVD-grown hetero structures based on In-Ga-Al-As-P solid solutions for more than 30 years no

We are promoting laser lamps, galvos, marking heads, green laser pointers etc till the stock is sold out. Pleasee click here.

STC Series Laser Diodes

We provide laser diodes with free space and fiber coupling option from 405-1550 nm wavelength range. The free space laser diode can be divided in to single mode and multimode. The fiber coupled laser diode can be divided into SM, PM, MM pigtailed and high power laser diode module. The small emitting aperture, combined with low beam divergence, make these devices the highest-brightness family of CW laser diodes available in the industry.diode laser

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.

 multi-wavelength diodesFeatures:

Applications:

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.

STL Series High-Power Fiber-coupled Diode Lasers

The diode laser offers remarkable laser beam quality with high brightness and high optical power density. The CW optical power of up to 1000 W is delivered through various fibers with small fiber core diameter from 100 µm to 600 µm. Small numerical aperture of 0.22 yields the perfect beam source for your application.

All systems are also available with power supply and/or cooling unit. We can offer you our fibre-coupled laser systems with the wavelengths of 808 nm, 915 nm, 940nm and 980 nm.
