Abstract: | In many applications, the laser beam needs to be focused to a very small spot size, or else the overall brightness of the beam is crucial parameter. In this study, the BeamStar CCD Laser Beam Profiler was used as a diagnostics measurements systems of passive Q-Switched laser beams. The dye laser was utilized as a source of Q-Switching laser. Two materials were used as a saturable absorber inside the laser cavity, which are 1,3'-Diethyl-4,2'-quinolyloxacarbocyanine Iodided (DQOCI) and Chromium-doped Yttrium Aluminum Garnet (Cr4+:YAG) Crystal. The output characteristics of the Q-switch laser posses of a uni phase of TEM00 mode. Laser parameters such as beam width, Gaussian Width and correlation were observed at various working distance. In general, the beam spot of passive Q-switch laser are independent with working distance. |
