title: Increasing output energy from a passively Q-switched Er:glass laser.
abstract: A method for increasing the output energy from newly developed passively Q-switched Er:glass eyesafe lasers is presented. The increase of energy is achieved by incorporating binary phase elements inside the laser cavities. Experimental results reveal that the output energies can be increased by more than a factor of two. Moreover, by manipulating the output phase with the binary phase elements, the peak energy density in the far field is increased by more than a factor of 4.5.
