Why are lasers so awesome? Because of our vacuum sintering oven auxiliary!

The industrial chain of laser processing has formed a complete ecological chain of laser processing from enterprises producing core lasers upstream to enterprises producing various kinds of laser processing equipment and then to enterprises providing laser processing services.

With its excellent processing performance and high efficiency, more and more laser processing equipment can be seen in the production of various advanced manufacturing industries.

The laser processing equipment mainly consists of laser optical processing system, mechanical transmission system, electronic control system and auxiliary system.

Laser optical processing system is the most core part, the cost of the highest proportion, it includes the laser, laser processing head and optical components.

In general, the laser is the core component of laser processing equipment, as important as the CPU is to the computer. It is the component with the highest technical content in the laser equipment accessories and occupies the core position in the laser industry chain.

Types and components of lasers

The laser is generally composed of three parts: working matter, excitation energy (optical pump) and optical resonance cavity.

The working material is the core of the laser. Only the material that can realize the energy level transition can be used as the working material of the laser.

Excitation energy (light pump) ACTS to give energy to the working matter, that is, the external energy of atoms excited from low level to high level;

The optical resonator is an important part of the laser. Its function is to make the stimulated radiation of the working material continue, to accelerate the photons, and to limit the direction of laser output.

Since the first ruby laser came out in 1960, laser technology has changed constantly.

In terms of working media, lasers are mainly divided into solid state (YAG) lasers, CO2 lasers, fiber lasers and other types, which have different performance and application fields.

High power laser vacuum sintering oven

Among them, fiber laser as the third generation of laser, its performance advantage is obvious.

Fiber laser refers to the glass fiber doped with rare earth element as the gain medium and pump source, coupler, resonator and other components of the laser.

The basic principle of optical fiber laser is: the pump sources are used by one or more of the high power laser diode array, the pump from the special pump structure coupled into the fiber as gain medium rare earth doped element, pump wavelength of the photon is absorbed by the doped fiber media, form the population inversion and stimulated radiation wavelengths by the resonator mirror feedback and oscillation laser output.

With the characteristics of high efficiency and low maintenance cost favored by system integrators, fiber lasers have become the future development direction of industrial lasers, gradually replacing the traditional solid state lasers and CO2 lasers in many fields.

Analysis of laser market development

In recent years, benefiting from the overall prosperity of the laser industry, the laser market has been expanding.

Data show that in 2016, the domestic laser market size of more than 7 billion yuan, the potential market size will reach 30 billion yuan.

However, the vast majority of domestic laser market share is occupied by foreign enterprises.

In 2016, IPG share in domestic laser market exceeded 50%, reaching 52.7%.

The leader, ruike laser, is next, but with a market share of 12.10%, a huge gap with IPG.

Fortunately, with the more and more extensive application of laser technology and the gradual mastery of laser technology by domestic enterprises, the pace of localization of laser market is accelerating.

Take fiber laser as an example, ruike laser and other products began to be commercially shipped in recent years, gradually breaking the monopoly of foreign enterprises in the field of fiber laser, but also gradually lower the price of imported products.

According to the power division, at present, low-power fiber laser less than 100W has been basically localized, the localization rate of fiber laser less than 1.5kw has reached 60%, while the localization rate of high-power fiber laser more than 1.5kw is only 11%.

In 2017, the domestic demand for high-power lasers exceeding 1.5kw was 4,700, up 47% year-on-year, of which 4,200 were imported, with a very high level of external dependence and huge space for domestic replacement

High power laser localization is difficult, on the one hand, in the epitaxial materials and chip field of professional research and development personnel is very scarce, concentrated in the United States, Germany, Britain, Japan and a few other countries.

On the other hand, the early stage of research and development investment is large, in the case of product sales expectations are not clear, invested a large amount of money to develop the laser several subdivided industries of software solutions greater risk.

At the same time, in order to meet the needs of different industries, the subsequent technical update and product upgrade also need a large investment in research and development and financial support.

In addition, large-scale production requires a large number of test and inspection instruments and production process equipment, which also requires a large amount of capital investment.

TORCH has developed special vacuum welding oven, vacuum sintering oven and vacuum annealing oven for high power laser industry.

In 2014, TORCH was awarded the "national torch technology industrialization demonstration project certificate".

After five years of continuous upgrading, TORCH in high power laser vacuum reflow welding technology is becoming more and more mature, can completely replace the vacuum furnace in Germany and the United States.

At present, it has been successfully applied by many famous domestic enterprises in the field of high power laser.
