Below we have a look to several applications of semiconductor lasers:

Semiconductor quantum well laser power in the precision machinery parts of the laser processing has important applications, but also become the most ideal, efficient solid laser pump light source. Because of its high efficiency, high reliability and advantage of miniaturization, leads to a solid laser constantly updated.

In the printing industry and medical fields, high power semiconductor lasers have also been used. In addition, such as the long wavelength laser ( 1976, people use Ga [nAsP / InP realize a long wavelength laser ) is used in optical communication, short wavelength laser used for optical disk readout. Since NaKamuxa implementation of GaInN / GaN blue laser, visible semiconductor laser in optical disc the system obtained the widespread application, such as an CD player, DVD system and high density optical storage visible surface emitting lasers in CD, printer, display all have very important applications, especially red,

Green and blue surface emitting laser is widely applied. Semiconductor blue-green laser for underwater communication, laser printing, high density information reading and writing, in deep water exploration and application in large screen color display, high definition color television sets. In conclusion, visible semiconductor laser is used as light source in color display, optical memory read and write, laser printing, laser printing, high density optical storage systems, bar code reader and solid laser pump source fields have a wide range of uses. Quantum cascade laser novel laser applied in environmental detection and medical fields. In addition,

As semiconductor laser can be changed through the magnetic field or current regulation of wavelength tuning is achieved, and has a very narrow line width can be obtained of the laser output,DVB Manufacturer so the use of semiconductor laser for high resolution spectroscopy study. The tunable laser is the in-depth study of the material structure and the rapid development of laser spectroscopy are important tools for high power infrared ( 3.5lm ) LD in the infrared countermeasures, infrared illumination, laser radar, atmospheric window, free space communication, atmospheric monitoring and chemical spectroscopy is widely used.

The green light to ultraviolet vertical cavity surface transmitter in optoelectronics are widely used, such as ultra high density, optical storage. The near-field optical scheme was considered to achieve high density optical storage is an important means. Vertical cavity surface emitting lasers can also be used in flat panel display, a large area of panchromatic transmitting, lighting, signal light, decorative light, ultraviolet lithography, laser processing and medical aspects of I2 ), as mentioned before, the semiconductor laser since nineteen eighties first since, because of the achieved DFB dynamics of single longitudinal mode laser was successfully developed and applied, quantum well and strained layer quantum well laser, high power laser and it 's progress, visible light the successful development of the laser, surface emitting laser, unipolar injection semiconductor laser diode and a series of major breakthrough, semiconductor lasers are used more and more widely, the semiconductor laser has become the main part of the laser industry, at present has become a national development of information, communication, household appliances industry and military equipment indispensable basic device.

Semiconductor laser in semiconductor laser marking machine and its application:

Semiconductor laser due to its long service life, high utilization efficiency of heat energy of laser, YAG laser small, small volume, high performance-price ratio, electricity saving and a series of advantages and become the product of E laser in 2010, domestic production of semiconductor lasers, accelerated to semiconductor laser as the main supplies of semiconductor laser replace the YAG laser marking machine market pace.
