讲座内容简介：

Photonics lasers, mainly semiconductor lasers or laser diodes (LDs), were successfully invented in 1962 and achieved the continuous wave (CW) output at room temperature in 1970. Later, photonics lasers were improved to develop several configurations with the double-heterostructures (DHs) and the stripe structures, etc. Until now, photonics lasers have been widely used in optical fiber communication, optical discs, laser printers, laser scanners, laser pointers, and are the largest laser type in production at present. The advantages of photonics lasers are high efficiency, small size, light weight, and low price. In particular, the conversion efficiency of the multi-quantum well (MQW) typed LDs is 40-60%, and in a word, the high energy efficiency should be their biggest merit. In addition, the continuous output wavelength covers from the THz-infrared to the visible-UV range, and the light pulse output of several tens watt products have also been commercialized. As liDAR or pump light sources, photonics lasers are very easy to use. They are mature earlier with faster progress because of their wide wavelength range, simple production, low cost, easy to mass production, and small size, light weight, and long life, etc. Therefore, photonics lasers should be the laser sources with the variety of rapid development, wide range of applications, most technical promising, and most market potential in the future.
