Schneider, I; Afzal, R S

A color center laser is provided with a crystal disposed within a longitudinally pumped cavity. Optics are provided to transversely excite the crystal. Both a circular lens and a cylindrical lens-focus an auxiliary beam into the crystal of the color center laser to produce (F2 + )A color centers for lasing. The cylindrical lens is used to focus the auxiliary beam to a narrow focal line. The circular lens is used to adjust the length of the focal line. By adjusting the length of the focal line, an entirety of the pump beam is used for excitation. The lenses thus collimate and focus the focal line to a length within an active volume in the crystal of the color center laser essentially equal to a length of the crystal.
