A connection between a device such as a computer or an electronic switch or between its internal boards is used, and a large number of channel electrical wiring is used. In these electrical wiring, if the signal transmission speed of each channel becomes an order of magnitude of Gbit / s, the crosstalk of the phase can not be ignored. In addition, in the use of electrical transmission, the basic consumption. Power, but also a problem. The so-called optical interconnection technology that converts these electrical wiring into optical wiring has recently revealed head and feet. Especially in the 10 channels around the channel transmission speed of lGbit / s parallel light mutual module needs to increase. The specifications of the module in recent years have been sold overseas. As this side-by-side burning laser pointer light source, there are now two kinds: one is a light source using a surface-emitting laser array; the other is a side-luminescent laser array. Both in a low-priced competitive state.
Optical fiber transmission laser welding machine is the use of energy fiber, the solid-state laser generated 1064nm laser, through the laser coupling technology to the fiber, and then the fiber in the laser through the output mirror to the workpiece surface, to achieve the purpose of welding; Laser, you can use the flexibility of the fiber, so that the laser can be any angle on the workpiece processing, to achieve a multi-dimensional flexible processing; fiber on the laser energy and homogenization of the laser spot energy can be modeled output, and laser Homogenization, so that the laser beam quality is better to improve the quality of welding.
After the optical fiber transmission by the laser light speed of good quality, spot fine, uniform energy distribution; initial section of power stability, change small, improve product qualification rate. It is believed that with the laser equipment line to the energy negative feedback fiber 500mw laser pointer welding machine research and development efforts to increase the energy negative feedback fiber laser welding machine development will be getting better and better. In layman’s terms, energy feedback can well control the average distribution of the speed of light and reduce the unevenness of welding.
A luminescent laser at the research stage, such as a light source for a laser printer. Now the laser printer is the side of the luminescence of the laser beam emitted by mechanical vibration mirror or multi-faceted mirror separated, and thus printed. If this part of the structure into large-scale surface-emitting lasers laser array, direct projection, then the printing speed can leap to improve the structure is also greatly simplified, which will revolution. Semiconductor surface-emitting lasers Current situation With the oscillation of different wavelengths, semiconductor surface-emitting lasers research and development situation is also very different.
Laser welding process of the results of the nickel-based alloy nickel-based tungsten carbide and nickel-based tungsten carbide rare earth alloy high power laser pointer cladding layer of the organization, the structure of the room temperature and high temperature hardness, corrosion resistance at room temperature and high temperature wear resistance corrosion wear performance The quantitative relationship between the corrosion wear rate, the dynamic wear rate and the dynamic corrosion rate was established on the basis of the above research, and the laser welding was applied to the mass production of the 200mw green laser cladding layer. Exhaust valve tooling fixture and automatic control device using the device on the car engine valve disc surface surface strengthening, finished rate of 98.5% The main technical performance indicators: 1. Wear resistance than GCr15 steel increased by 3 to 10 times.
