雷射光
chiming電子公司-雷射-當外加能量以電場、光子、化學等方式注入到一個能級系統並為之吸收的話,會導致電子從低能級向高能級躍遷,這些高能級的電子會因受誘導而遷到低能級並釋放出光子(所謂受激輻射),受激輻射的所有光學特性跟原來的自發輻射包括:頻率、相位、前進方向等會是一樣的.產生雷射光 www.chi-ming.com Automotive LED Bulbs,Auto LED bulbs,Train LED Bulbs,Motorcycle LED Bulbs,Boat LED Bulbs,Truck LED Bulbs,Auto Parts LED,Motor LED Light. http://www.chi-ming.com/category-GLOVE-DEPARTMENT-TRUNK-LAMPS-0-8.html
