  • 激光器件的起源與發展

    光纖通信所需的光源,應該是可高速調制的光源,以便載送大容量信息。如激光器和發光管。所謂“調制”就是按照所要傳輸的信息來改變光的強度等,以承載信息。

    1960年邁曼(Maimen)發明紅寶石激光器。激光(Laser)與通常的光線的不同之處主要在于激光的光頻非常單純,具有線狀譜線,光學中稱為相干光,最適合做光纖通信的光源。而通常的光線的光頻十分雜亂,它包含許多波長。而通常的光線的光頻十分雜亂,它包含許多波長。相干光的特點是光能集中,是發散角很小,近似平行光。在紅寶石激光器發明后,各色各樣的激光器相繼誕生: 有氣體激光器,如氦氖激光器;有固體激光器,如YAG銥鋁石榴石激光器;有化學激光器;染料激光器等。其中半導體激光器管家婆四肖八码免费长期公开最適合作光纖通信的光源,它的體積小,效率高,它的波長同光纖的低損失窗口相適合。

    在傳感方面,激光器用于相位型、波長型、光強型和偏振態型光纖傳感中。在石油或天然氣井中可測量溫度和壓力;在道路、橋梁和船殼中可測量應變;在飛機機翼中進行飛行健康監控;還能應用于光纖水聽器和電流傳感中。激光物位計,激光液位計,激光測距傳感器,激光料位計,激光物位儀,激光柜位計,煤氣柜激光物位,煤氣柜柜容儀,煤氣柜激光柜容儀,激光式物位計,煤氣柜活塞傾斜測量,煤氣柜活塞平衡,激光水尺,激光電子水尺,激光水位計

    在工業方面,激光器已經在金屬和非金屬材料的加工與處理、激光雕刻、激光產品打標、激光焊接、焊縫清理、精密打孔和激光圖形藝術成像等方面很有作為。

    在醫療方面,激光器因其體積小、光纖柔軟性好,光束質量好,且不需冷卻系統,已經得到了廣泛的應用。光纖激光器管家婆四肖八码免费长期公开使能縮短組織脫落和光致凝結的手術時間:同時使得眼科疾病如角膜成形、近視、遠視等的治愈成功率大大提高。還在整容、切除腫瘤、治癌、皮膚病方面扮演重要的角色。

    在軍事方面,高功率激光器以其高亮度,小照射面積,體積小而倍受親睞。作為武器可以精確的瞄準打擊并摧毀目標,另外在定位、測距、遙感、跟蹤制導、激光雷達系統傳感技術和空間技術等方面有著重要意義。
