激光二极管具有体积小、功率大、重量轻、耗电省、可靠性高、波长短等特性。在诸多应用领域内,它与其它气体、固体激光器相比毫不逊色,且已广泛应用于光电、视听、光盘、光纤通信、外科医疗、激光打印、位置传感器等领域。目前,极短波长的650-690nmAlInGaP激光二极管已商品化。高辉度黄色发光二极管日本YHP公司推出一种目前世界上辉度最高的黄色发光二极管。发光波长590nm,发光效率20
Laser diode with small size, high power, light weight, low power consumption, high reliability, short wavelength and other characteristics. It is comparable to other gas and solid-state lasers in many fields of application and has been widely used in the fields of optoelectronic, audiovisual, optical disks, optical fiber communications, surgical medical, laser printing, position sensors and the like. Currently, very short wavelength 650-690nm AlInGaP laser diode has been commercialized. High-brightness yellow light-emitting diode Japan YHP company introduced a currently the world’s highest brightness yellow light-emitting diode. Luminescence wavelength of 590nm, luminous efficiency of 20
