摘要
研究了大功率短脉冲垂直腔表面发射激光器(VCSELs)出光孔径分别为400μm,600μm的980nm倒封装底发射VCSELs的脉冲特性,通过测试脉冲电流源产生的电脉冲的波形曲线以及产生的光脉冲的脉冲响应曲线,得到脉冲峰值功率与输入电流的P-I曲线,600μm直径的VCSELs在脉冲宽度为60ns,重复频率为1kHz时,得到超过20W的峰值输出功率;激射波长为976.6nm,器件的光谱半高宽(FWHM)为0.9nm。
High power VCSEL（Vertical-Cavity Surface Emitting Lasers） has applications such as free-space optical communications and laser range finding.Two different aperture diameters 980nm,bottom-emitting VCSELs were used.The peak current trace and corresponding peak optical trace are also tested and analyzed.The relationship between the electrical pulse width and optical pulse width are discussed.Peak output power has been arrived more than 20W at 980nm wavelength while pulse width is 60ns and pulse repetition frequency is 1kHz.
