利用双膜系介质镜谐振腔产生30fs锁模脉冲
Generation of short pulse of 30 fs from a simple colliding-pules mode-locking dye laser with double coated stack mirrors
摘要
本文通过计算机叠代法,分析计算了一般所用的λ_m/4单膜系介质腔镜的色散,发现用这种腔镜难以补偿腔内脉冲的正啁啾.设计了一种双膜系介质镜,它具有补偿正啁啾所需的合适色散量φ(ω)=1.3×10~(-28)sec~2,用它代替一般腔镜,结果在没有附加任何其它色散元件情况下,直接从简单的碰撞锁模染料激光器获得30fs的脉冲输出.
Abstract
The dispersion produced by an ordinary single stack cavity mirror is analysed. This kind of mirror is difficult to compensate the upehirp of the pulses in the cavity. A kind of double ooated stack mirror, with the suitable amount of dispersion of φ(ω) =1.3 ×10~(-28) sec2 for upchirp compensation is designed and used as cavity mirrors, so that pulses as short as 30 fs are generated directly from a simple oolliding-pulse modo-locked (CPM) dye laser without additional dispersive elements in the cavity.
