PULSE WIDTH STRETCHER AND CHIRPED PULSE AMPLIFIER INCLUDING THE SAME

摘要

The present invention discloses a pulse width stretcher and a chirped pulse amplifier including the same. The pulse width stretcher may include first and second multiple reflection mirrors and a pulse group-delay dispersion block which is arranged between the first and second multiple reflection mirrors and refracts a pulse laser beam to stretch the pulse width of a pulse laser beam. So, space efficiency can be maximized.
