Abstract
Disclosed is a laser apparatus of amplifying a laser pulse output using an anisotropic laser crystal through chirped pulse amplification. The laser apparatus includes a laser resonator. The laser resonator includes a plurality of anisotropic laser crystals, generates a shorter femtosecond pulse by widening a spectrum bandwidth through a combination of different gain spectrum distributions using the anisotropic laser crystals, and allows a laser beam to travel in axial directions with different thermal characteristics of the anisotropic layer crystals in order to reduce a thermal effect.
