Abstract: A laser system includes first and second mirrors, a semiconductor laser and a high frequency pulse generator. The semiconductor laser generates optical power within an optical cavity and reflects the optical power between the first mirror and second mirrors. The optical power has a frequency of foriginal-laser. The high frequency pulse generator generates a high frequency pulse with a rise time greater than an optical cycle of the optical power within the optical cavity and directly impinges the high frequency pulse on the optical power within the optical cavity. Impinging the high frequency pulse on the optical power within the optical cavity causes a frequency shift of the optical power to generate a final laser frequency that is greater than foriginal-laser as well as beyond a frequency band of the second mirror to cause a final laser to be emitted past the second mirror and from the semiconductor laser.

Abstract: A projectile having a fin deployment system disposed about its circumference. The fins are initially contained by a fin cover that is removed by aerodynamic force. The fins are then rotated around a rotational axis parallel to and offset from the central axial axis of the projectile body by the centrifugal forces created by the rotation of the projectile as the projectile passes through a barrel of a gun system or tube launcher. The fin deployment system can also have locking systems that lock the fins in the deployed position and prevent the fins from rotating back into the retracted position after deployment.
