【Abstract】 The laser diode(LD) which is C-mount encapsulation,rated power is 2W and peak wavelength is 808nm is measured.It is measured in different temperature and formed the PIV curve,the spectrum curve,the far field characteristic curve.The thermal characteristic of the laser diode and the parameters change rule of laser diode in different temperature and the reason are analyzed.Dealt with the data and calculated temperature coefficient of wavelength k which is used connecting with the frequency bathochromic shift method to calculate the laser diode Rth thermal resistance value.The results prove Rth with temperature changes.更多还原
