Abstract:
1. A space based laser device comprising: a first gain material, said first gain material having an orientation along an axis for a symmetrical single spatial mode round resultant laser beam; a second gain material, said second gain material having an orientation orthogonal to that of the first gain material and along said axis; a waveplate disposed between said first and second gain materials along said axis; and energy means including a plurality of diodes disposed along said first and second gain materials providing a spherical symmetrical thermal lens spatially adjusted to maintain a circular shape by use of an adjacent end mirror with means for fine tuning the drive powers in each diode to reduce elliptical aberrations to pump energy into said first and second gain materials along a zig-zag optical path while allowing laser slabs to behave optically like cylindrical laser rods formed into a dual split head V-shaped gain module in order to reduce distortion and increase efficiency in a transmitted laser beam.
