摘要: 在共振腔內擺入飽和吸收體Cr4+:YAG晶體可得到高功率雷射脈衝輸出,而高功率雷射可應用在遠距離量測、雷達、醫療以及材料加工等方面。使用在雷射測距上之雷射,其脈衝產生時間之誤差是一嚴重變因,而本論文中,將探討不同共振腔下產生之橫模,其橫模中不同位置脈衝產生時間之差異。所得到之結果由最小幾百皮秒(ps)至最大幾十奈秒(ns)等級。
We can obtain high peak power laser with absorber inside cavity. High peak power lasers are applied to distance measuring, radar, medical system and industry marker process. The lasers which are used to be the distance measuring tools has a series pulse delay problem. In our thesis, we will discuss that the transverse modes of different cavities and the variation of pulse delays of different mode position. Delay in pulse arrival times from hundreds of picoseconds to several tens of nanoseconds can be observed in our experiment.
