Diode pumped, chirped mirror dispersion compensated, fs-laser

We demonstrate the first diode pumped, Kerr-lens mode locked fs-laser which is completely dispersion compensated by chirped mirrors. Low loss chirped mirrors together with advanced pump diodes permitted the generation of transform limited 65 fs pulses with a mode locked output power of 70 mW in a prismless cavity. The influence of intrinsic colquiriite properties on the pulse width is discussed, and a possible explanation of the low Hod-impact on the shortest pulses is derived.
