飞秒激光技术是当前激光前沿领域的发展内容之一,飞秒脉冲的压缩手段更是其中重要的研究内容。在飞秒脉冲的压缩中,必须使用负的色散元件来补偿飞秒激光钛宝石晶体本身所具有的正的色散以实现压缩。现有的负色散补偿技术包括使用以下三种方式:高密度光栅对、棱镜对、啁啾镜。这
Femtosecond laser technology is one of the development of the laser frontier field, femtosecond pulse compression means more important research content. In femtosecond pulse compression, a negative dispersive element must be used to compensate for the positive dispersion that femtosecond laser sapphire crystals have in themselves for compression. Existing negative dispersion compensation techniques include the use of the following three ways: high-density grating pairs, prism pairs, chirped mirror. This
