普克爾盒通過施加電壓到電光晶體重氫磷酸鉀DKDP (KD*P).的電極上，來改變光的偏振態(tài)。基于DKDP (KD*P).的普克爾盒通常用于Q開關(guān)，波長400-1100nm。多數(shù)的商用閃光燈泵浦Nd:YAG激光器和低重頻的DPSS Nd:YAG激光器的腔內(nèi)Q開關(guān)都是用的基于DKDP (KD*P)的普克爾盒。
DKDP (KD*P).普克爾盒特點(diǎn)：
- § 體積小
- § 低吸收率
- § 波段400-1100nm
應(yīng)用:
- § 激光腔Q開關(guān)
- § 腔倒空
普克爾盒內(nèi)的電光 DKDP (KD*P)晶體鍍有增透膜，部分型號的產(chǎn)品帶有保護(hù)窗口，適用于比較復(fù)雜的環(huán)境
