    Q開關(Q switch):. Q開關為一種調變方式，常見之Q開關調變方式是讓共振腔之Q值在高(低損耗)與低(高損耗)兩狀態間轉換，藉由調變雷射共振腔內的品質因子(Quality factor)，使得原本在時間上是連續輸出的雷射光源，透過Q開關之作用，讓雷射變為一脈衝式之雷射，其作用原理為，讓雷射共振腔大部分時間保持在Q值低之狀態，此時 ...

    Q開關雷射(Q-switched laser):. 雷射是利用增益介質外加能量，(通常以光通注入或是電流注入的方式)將雷射共振腔中具有較高態密度的雷射模場(波長、場分佈)以激發輻射的形式放大所產生的同調光源,. 在沒有調變機制下，雷射輸出功率是固定、不隨時間改變的。這樣的雷射稱為連續式雷射(CW Laser)。若加入調變機制，則可以形成 ...
