Also known as laser diode laser diode (LD).Into the 1980s,it absorbed the physical development of the semiconductor up-to-date results,the use of quantum well (QW) and strained quantum well (SL-QW) structures,such as novelty,the introduction of the refractive index modulation Bragg launchers,as well as to enhance Bragg modulation transmitter The latest technology,as well as the development of the MBE,MOCVD and the CBE,such as crystal growth technology of the new technology,making new epitaxial growth technology to precisely control crystal growth to the accuracy of atomic layer thick,high-quality growth of quantum wells,as well as strained quantum well materials.As a result,production of the LD,the current threshold of a significant decline in conversion efficiency has been greatly improved the power output doubled,significantly longer service life.
A low-power LD
In the field of information technology for the rapid development of low-power LD.For example,for fiber-optic munications and optical switching systems distributed feedback (DFB) and the dynamic single-mode LD,narrow linewidth tunable DFB-LD,such as CD-ROM for information processing technology in the field of visible light Wavelength (such as wavelength of 670nm,650nm,630nm The blue-green to red) LD,surface-emitting quantum well,as well as ultra-short laser pulses substantive,which are all treated the development of LD.The development of these devices are:narrow-linewidth single-frequency,high-speed,as well as short-wavelength tunable optical and integrated single-chip,and so on.
B high-power LD
In 1983,a single wavelength of 800nm output power LD more than 100mW,to 1989,0.1mm-wide LD be reached 3.7W continuous output,and 1cm linear array LD has reached 76W output,the conversion efficiency of 39%.In 1992,the Americans also targets to a new level:1cm linear array LD CW output power up to 121W,the conversion efficiency of 45%.Now,the output power of 120W,1500W,3kW and many other high-power LD have been published.High-efficiency,high power LD array and its rapid development for all-solid-state laser,diode laser that is pumped (LDP) of the rapid development of solid-state laser provides strong.
In recent years,in order to adapt to the EDFA and the EDFL,and other needs of the wavelength of 980nm high-power LD is that there is great development.Fiber Bragg
