Abstract:
In this research calibration of some laser equipment in the clinic of the laser institute of the university of Sudan(Omega xp and Orillia) was per formal together with some other devices (diode laser second harmonic, He- Ne ,diode).some laser parameters like (wavelength and FWHM )were calculated. The accuracy of each equipment was determined. The International method of calibration was used and the device USB 2000 with computer soft ware orgin6 was aslo used to find the Gaussian configuration and then calculation of some laser parameters. the results showed reduction in wavelength for all calibration devices compare to the standard wavelengths (1.65, 3.35,10.18,10.38,16.87)the calculation showed the high accuracy of some lasers equipment .
