The linear dimensions of the far-field beam patterns shrank in size by the end of radiation by 3%-20% for the IR lasers and 15%-20% for the visible. The ellipticity of the beams changed by -16% for the IR and +8% for the visible case. The intensity， as measured with an external camera， decreased during irradiation by a maximum of 2.7 dB for the visible laser and 2.5 dB for the infrared; however， the photodiode photocurrents changed by less than 1 dB. Both types of lasers recovered completely over several days. The near- and far-field patterns were examined both below and above threshold before and after radiatiodrecovery， with no evidence of defects or other gross changes.请不要用软件直接翻译！！
