Abstract

A broadband ultraviolet pulse with a spectral width of 44 nm was generated by achromatic sum-frequency mixing of an 805-nm pulse and ultrabroadband visible pulse. Angular dispersion was introduced to achieve broadband phase matching by a prism pair. The UV pulse was compressed to 13.2 fs with another prism pair, with energy of 600 nJ.

摘要

通过805纳米脉冲与超宽带可见脉冲的消色差和频混频产生了光谱宽度为44纳米的宽带紫外脉冲。引入角色散以通过一对棱镜实现宽带相位匹配。用另一对棱镜将紫外脉冲压缩至13.2飞秒，能量为600纳焦。
