There are many ways to classify semiconductor lasers. On the basis of the wavelength can be divided into the far-infrared laser, near-infrared laser, visible laser, ultraviolet laser, and other categories. Visible semiconductor lasers (wavelength 400~700 nm) are one of the important categories. The blue semiconductor laser is a semiconductor laser whose output wavelength is in the range of 400 -500 nm.

Laser processing refers to the use of laser beam projected on the surface of the thermal effect of the material to complete the processing process, including laser welding, laser cutting, surface modification, laser marking, laser drilling and micro machining. Laser can adapt to all materials processing and manufacturing, especially in some special precision requirements, special occasions and special materials processing and manufacturing has an irreplaceable role.

Lidar is an important sensor integrating laser, GPS positioning and inertial measurement device. Its wavelength is mainly located in the near infrared part of the electromagnetic spectrum (780nm, 808nm, 850nm, 940nm, 1064nm).With the emergence and development of intelligent vehicles, laser radar has a broader space.

The competition between countries is actually the competition of science and technology, in the field of science and technology, chip demand is everywhere, chip has become the core of the competition among countries in the world.Under the background of global "lack of core", the road of independent chip research and development in China's technology industry is imminent.Under the guidance of the 14th Five-year Plan, the inclination of social resources and the introduction of countless funds, the domestic chip industry will take advantage of the situation into the fast track of vigorous development.

Short-wave length infrared band referred to as"SWIR”. SWIR located in the non-visible spectrum between near infrared (NIR) and long wave infrared (IR).The general wavelength range is 1400-3000nm, which contains rich material spectral information.

Fiber lasers set a new standard for the laser processing industry due to their ultra-high reliability, excellent beam quality, and low operating costs.At the same time, fiber laser has the characteristics of small volume, low energy consumption, long life, high stability, multi-band, green environmental protection, long gain medium, high coupling efficiency, good heat dissipation, simple and compact structure, so that it has won the affirmation of many laser industry.If you want to switch to fiber pigtailed lasers, how much can you save?

Laser technology is considered to be one of the essential tools for human survival and development in the intelligent society.Such as sweeping robot, vehicle-mounted laser radar and so on.At present, major countries in science and technology attach great importance to the research and application of laser technology, China also attaches great importance to the research and application of laser technology, such as high efficiency and precision laser additive manufacturing - ecM overall manufacturing technology, femtosecond laser precision manufacturing application basic research projects in the national Key RESEARCH and development program.

Laser diodes are the hidden champions of modern laser technology.Laser diodes are everywhere, from simple laser Pointers to complex quantum communication satellites.It has excellent efficiency, compact structure, numerous types, many people have considered to use laser diode in their own products, facing a variety of laser diode diode, engineers how to choose?

Laser is a kind of device which can emit laser and is one of the essential core components in modern laser processing system.With the development of laser processing technology, many new lasers are coming out.Because the laser has high brightness, good monochrome, good direction and coherence and other outstanding characteristics, so it is used in industry, agriculture, precision measurement and detection, communication and information processing, medical, military and other aspects, and caused a revolutionary breakthrough in many fields.Laser in the military in addition to communications, night vision, early warning, ranging and other aspects, a variety of laser weapons and laser guidance weapons have also been put into practice.

Semiconductor laser, also known as laser diode, is a semiconductor material as the working material of the laser.It is generally composed of laser working material, excitation source, concentrator, resonator mirror and power supply.The solid working substance used in this kind of laser is made of mixing metal ions which can produce stimulated emission into crystals.

Fiber laser​ is refers to the element with rare earth doped glass fiber as gain medium laser, fiber laser can be developed on the basis of the optical fiber amplifier: within the optical fiber under the action of the pump are high power density, causing the laser work material laser level "population inversion", as appropriate to join the positive feedback loop (a cavity) can form a laser oscillation output.
