 What I'm going to talk about today is 660nm 1800mW fiber laser system . It supports 3 working modes, CW/TTL/Analog. In TTL/Analog modulation mode, an external modulation signal needs to be connected. In addition, the Lock crystal head cannot be pulled out. External signal Mod Input, no need to connect in CW working mode. To adjust the output power by adjusting the working current: Turn the 'Adjustor' knob clockwise, when the current exceeds the minimum working current, the Laser indicator light turns green, and there is laser output at this time. When the 'Adjustor' is rotated clockwise to the end, it is the max working current and the max output power of the laser. In addition, the red STOP button is used for emergency stop, and it is not used under normal circumstances. The optic fiber can be customized. Here is 1000μm SMA905 interface fiber. 100μm to 1000μm fiber is optional, the coupling efficiency of different fibers will be somewhat different. The larger the...

 This is a 543nm solid state laser system . The output power is 100mW, it can be adjusted by the rotary button on the power supply. There are 3 working modes for the laser to choose from. Select the working mode CW/TTL/Analog by the sliding button on the back of the power supply.  The red button is the power switch. The key is a laser switch. The middle LCD shows the current working current. The rotary button on the right is to adjust the current size.   This laser coupled a 1000μm, 3 meters in length, SMA905 interface fiber, and its can be customized. The effect of laser output from the fiber port:

 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...

In 2019, the materials processing sector has a significant market share, and this trend is expected to continue over the forecast period. Factors such as the processing and manufacturing of small electronic components will play an important role in the field of materials processing to maintain their market position. However, macroeconomic factors such as limited supply of rare earth elements, the existence of alternatives, and slowing economic growth may hinder the growth of the fiber laser industry over the forecast period. Increased demand for fiber lasers in additive manufacturing Fiber lasers are an important part of the additive manufacturing process. This process greatly reduces material waste, reduces the number of production steps, reduces the number of stocks and the different parts required for assembly. In addition, metal-based 3D printing processes, such as laser material deposition and selective laser melting, use fiber lasers to weld metal powders to produce high...

Lasers  are widely used in home appliances, medicine, industry, telecommunications and other fields. A few years ago, scientists introduced the concept of nanolasers. Their design is similar to traditional semiconductor lasers based on heterostructures that have been used for decades. The difference is that the cavity of nano lasers is very small, proportional to the wavelength of the light they emit. Since they mainly produce visible light and infrared light, their size is about one millionth of a meter. Nano lasers  have unique properties that are distinct from macro lasers. However, it is almost impossible to determine under what current the output radiation of a nanolaser is coherent; in addition, for practical applications, it is important to distinguish between two states of a nanolaser: a real laser effect with coherent output at high currents and a LED-like state with non-coherent output at low current. Researchers at the Moscow Institute of Physics and Tech...

EDFA fiber amplifier, also known as  erbium-doped fiber amplifier , is a major breakthrough in fiber-optic communication technology because it can directly amplify weak optical signals without undergoing optical-electrical-to-optical conversion. Besides, what do you know about EDFA fiber amplifiers? Many people may answer "No". It doesn't matter if you don't understand it. This article will analyze EDFA fiber amplifiers in the following aspects to let you know more about it. Why use an EDFA fiber amplifier? There are many different bands in the transmission process, such as C-band (1530nm-1560nm) and L-band (1560nm-1600nm). Because different wavelengths are different, communication will be affected, so it is necessary to amplify the cross-section of the fiber link. The band channel can guarantee normal communication effects. The EDFA fiber amplifier just meets this need by using a residual fiber as a gain medium to amplify the optical signal and amplify a wide ...
