It's a 450nm high power laser system, the max output power is 50000mW . Heat sink can be added to laser head. And the output power can be adjusted by adjusting the current. This laser has three working mode: CW/TTL/Analog modulation. Let's check it now.

1 Introduction As a light source  of fiber laser sensor, narrow linewidth fiber laser has the characteristics of interference to electromagnetic field, safety, small size and remote control. Currently, there are three schemes for obtaining single longitudinal mode narrow linewidth fiber lasers. 1) Non-coherent technology that eliminates spatial hole burning caused by standing wave effect by controlling the polarization state of the encountering light waves in the cavity; 2) adding unpumped doped fiber in the laser cavity to select the frequency and suppressing the saturated absorption of the mode-hopping Body; 3) short cavity fiber laser, including DFB fiber laser and short cavity DBR fiber laser. Comparing the three schemes, it is found that schemes 1 and 2 require the use of multiple polarization controllers, and most of them have annular cavity structures, which are difficult to control, low conversion efficiency, and extremely low output power; while scheme 3 has a simple stru...

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...

It's a red  fiber coupled laser , wavelength is 685nm. There are 3 working mode,  CW and TTL/Analog modulation . When use modulation work mode, the laser need be inputed 0-5V signal at ‘Mode Input’ BNC interface. Let's check it.

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...

Since the advent of the first 10,000-watt laser cutting machine in 2017, the application of ten-thousand-watt lasers has become an industry hot spot. In 2018, as nearly 20 domestic laser equipment manufacturers successively launched 10,000-watt laser cutting machines, more laser companies also stepped up their plans to follow up with the introduction of domestic-made 10,000-watt lasers. There is a strong "arms race" posture. In 2019, 20,000 watts, 30,000 watts, and even higher power devices have been unveiled at major exhibitions at home and abroad, and the pursuit of higher power devices seems to be a trend. It is undeniable that the increase in power has brought some process innovations, while providing more choices for the metal cutting market, and also improving production efficiency. On the other hand, excessive emphasis on high power laser has also created some undesirable phenomena. Some companies blindly follow the trend and one-sided pursuit of high power, but ...
