1.3微米波长InGaAsP激光器产生的亚微微秒光脉冲的干涉自相关测量

Interferometric Autocorrelation Measurements of Subpicosecond Optical Pulses from 1.3μm Wavelength InGaAsP Diode Laser

建立了用步进电机扫描的干涉自相关仪。测量了用1.3微米波长InGaAsP激光器产生的0.45ps的光脉冲。根据干涉自相关函数判定该脉冲是没有调制偏移的双曲正割型光脉冲。

Aninter-ferometric autocorrelator scanning with step electric motor has been set up. Optical pulses with 0.45 ps FWHM from a 1.3 μm wavelength inGaAsP diode laser have been measured. According to the interferometric autocorrelation results, the pulses are unchirped hyperbolic secant pulses.
