A corner reflector (2) is applied for a laser head to couple collimated pump beams (3) emitted from one or more diode bars (5, 8) transversely into the laser rod (1) with an even 4-sided pumping. A Keplerian telescope (23) with internal nonlinear crystal (27, 37) is employed for a compact cavity design, to achieve mode-matched pumping, compensation of the thermal lens effect, and efficient intracavity frequency conversion.
