摘要
报道980nm大功率底发射垂直腔面发射激光器的结构、研制及器件的阈值电流、输出功率和光谱特性.在室温(24℃)下,5A连续电流工作时,出光孔径400μm的器件激射波长为984.1nm,输出功率达到1.42W,是目前所能见到报道中最高的.研究了出光孔径600μm的器件在连续工作时,激射波长、光谱半高宽随注入电流的变化以及在重复频率100Hz,脉冲宽度50～1000μs条件下的输出功率、效率与注入电流的关系.
Abstract
The structure design and fabrication process of 980nm high power vertical-cavity surface-emitting laser diodes (VCSELs) were reported. The threshold current, output power and spectrum characteristics were investigated. An optical output power as high as 1.42W for a 400μm diameter device was achieved at room temperature. To our knowledge, this is the highest record for a single device up to now. The dependence of the CW emitting wavelength and FWHM of spectrum of a 600μm diameter device on injection current indicated the heating effects in the active region. The output power performance was further characterized by using pulse operation with pulse width from 50~1000μs.
