| description | A laser apparatus including an optical element made of a CaF2 crystal and configured to transmit an ultraviolet laser beam obliquely incident on one surface of the optical element, the electric field axis of the P-polarized component of the laser beam propagating through the optical element coinciding with one axis contained in of the CaF2 crystal, with the P-polarized component defined with respect to the one surface. A method for manufacturing an optical element, the method including causing a seed CaF2 crystal to undergo crystal growth along one axis contained in to form an ingot, setting a cutting axis to be an axis inclining by an angle within 14.18±5° with respect to the crystal growth direction toward the direction of another axis contained in , which differs from the crystal growth direction, and cutting the ingot along a plane perpendicular to the cutting axis. |
