 Usually we often see visible lasers, but few people will test infrared invisible lasers. Today we tested a 915nm infrared laser and its output power of 3000mW. Then when it is coupled through the fiber, what is the output power of the fiber end? Let's check it now. This is 915nm 3W IR semiconductor laser. It couples a pluggable optical fiber . The fiber can be customized. 100μm~1000μm fiber is optional, the coupling efficiency of different fibers will be somewhat different. The larger the core diameter, the higher the coupling efficiency, usually the coupling efficiency is 80%~90 percent. In addition, the fiber length and interface also can be customzied. Here is 1000μm, SMA interface fiber. CivilLaser's solid-state lasers can be customized for fiber-coupled output.  The output power of the laser is adjustable from 0 to 3000mW, which can be adjusted by the knob. It supports 3 working modes, CW/TTL/Analog, switch the working mode on the back of the laser power supply. In TTL/...

 The 2200nm multimode fiber-coupled laser is fiber-coupled with a 2200nm semiconductor laser to obtain fiber output. The coupled fiber output laser power stability is good, the spot pattern can be improved, and the collimated beam can meet the demand for high beam requirements. This is a 2200nm 300mW laser system with 400μm fiber. The fiber is pluggable, and it's interface can be customized according to customer needs. It supports two working modes: CW and Modulation. The laser output power is adjustable by rotating the silver-white rotary button.  The middle display shows the magnitude of the current. The higher the current, the higher the output laser power. The test report for the 2200nm laser .

 This is 445nm 24W high power semiconductor laser . The power supply has LED display, which can display the current working current. The 'Adjustor' knob is used to adjust the current to control the output power. On the back of the laser power supply, there are 3 working modes to choose from: CW, TTL and Analog. The laser head can be customized to add heat sink, fiber coupling can also be custom added. Demonstration of laser operation: Connect the AC power cord. Slide the working mode to CW, continuous light mode. Connect the laser head and laser power supply. Insert the key. Turn on the power switch, the red button goes to ON. Then turn on the laser control key, the key turns ON. Rotate the knob Adjustor to adjust the laser output power to a suitable size. Important reminder: It is strictly forbidden to irradiate the human body with laser light, especially the eyes. Laser protective glasses must be worn during operation. This 24W high-power laser , the reflected light may als...

 It's a 635nm 15W High power red laser system. 15W is a high-power laser, which generates a lot of heat after working for a long time. We have added a heat sink base to the laser head. The bottom heat sink has 2 cooling fans. This is a fiber coupled laser . The 400μm fiber is pluggable, and it is equipped with a collimator at the fiber output end. Let's check it now. This is the light output effect of the laser head without optical fiber. At this time, the light spot is not concentrated. After adding the optical fiber, the light spot is circular, and the NA (Numerical Aperture) of the optical fiber is 0.22. The light output effect of the fiber light outlet plus the collimator, the focal length of the collimator is adjustable.

Let's check it now.  

A systematic study of a simple and general structure for on-chip semiconductor lasers by A*STAR researchers sets the scene for much broader application of integrated semiconductor lasers beyond conventional silicon-based systems. The ability to use, manipulate and sense light is applicable to many technologies, from data interconnection and fiber optics to optical sensors and optical storage systems. One such non-silicon-based application is a new type of data storage system called heat-assisted magnetic recording (HAMR), which researchers at the A*STAR Data Storage Institute have been working on as a next-generation data storage technology. HAMR uses integrated lasers for fast and precise micro-spot heating of a magnetic medium, but requires the laser to be formed on aluminum-titanium-carbide (AlTiC) rather than silicon. This presented Chee-Wei Lee and his colleagues with a significant problem, since the silicon substrate plays in integral role in producing the laser light. ...

The year is ending, holiday reminders surround us, and after some opulent dinner it is time to think about what may come to us next year. A few trends in photonics such as lidar or additive manufacturing are obvious, others may be less apparent. Here are my picks for photonics trends that might be worth watching in 2018. 2017 was an incredible year for industrial photonics: Market leaders such as Trumpf and IPG Photonics posted double-digit revenue growth, and Coherent seems to do well with the purchase of Rofin Sinar. It is no surprise that fiber lasers conquered more than 40% market share, while the good news for excimer lasers may not be on everybody‘s focus. And thanks to EUV the good old CO2 laser has some new prospects as well. Behind many of the good numbers is a record breaking spending of almost $56 billion for equipment in semiconductor industry. The CEO of Carl Zeiss, Michael Kaschke, spoke of “the most successful fiscal year in the history of Zeiss,” backed by a 25% in...
