1030nm laser diode Manufacturers

In the industrial laser application, people usually use 915nm pumping in the past, but with the rapid development of fiber lasers, the market demand for higher power has become more and more prominent, and competition is becoming increasingly fierce. The 915nm wavelength has lower absorption efficient which brought double obstacles in cost and technical, limiting the development of high-power and low-cost fiber coupled laser modules.

In recent years, with the continuous expansion of pulsed laser applications, the high output power and high single pulse energy of pulsed lasers is no longer a purely pursued goal. In contrast, the more important parameters are: pulse width, pulse shape and repetition frequency. Among them, the pulse width is particularly important. Almost just by looking at this parameter, you can judge how powerful the laser is. The pulse shape (especially the rise time) directly affects whether the specific application can achieve the desired effect. The repetition frequency of the pulse usually determines the operating rate and efficiency of the system.

In the mid-1980s, Beklemyshev, Allrn and other scientists combined laser technology and cleaning technology for practical work needs and conducted related research. Since then, the technical concept of laser cleaning (Laser Cleanning) was born. It is well known that the relationship between pollutants and substrates The binding force is divided into covalent bond, double dipole, capillary action and van der Waals force. If this force can be overcome or destroyed, the effect of decontamination will be achieved.

Everyone must have heard the slogan "femtosecond laser for myopia", but I believe many people don't know what femtosecond laser is. Similarly, there are nanosecond laser and picosecond laser. What's the difference between these strange seconds and our common lasers?

Optical fiber amplifier refers to a new type of all-optical amplifier used in optical fiber communication lines to achieve signal amplification. Among the currently practical fiber amplifiers, there are mainly erbium-doped fiber amplifiers (EDFA), semiconductor optical amplifiers (SOA) and fiber Raman amplifiers (FRA). Among them, erbium-doped fiber amplifiers are now widely used in long-distance applications due to their superior performance. It is used as power amplifier, relay amplifier and preamplifier in the fields of long-distance, large-capacity and high-speed optical fiber communication systems, access networks, optical fiber CATV networks, systems (radar multi-channel data multiplexing, data transmission, guidance, etc.).

The principle of the photodetector is that the conductivity of the irradiated material changes due to radiation. Photodetectors are widely used in various fields of military and national economy. In the visible or near-infrared band, it is mainly used for ray measurement and detection, industrial automatic control, photometric measurement, etc.; in the infrared band, it is mainly used for missile guidance, infrared thermal imaging, and infrared remote sensing. Another application of the photoconductor is to use it as the target surface of the camera tube.
