摘要:

We have constructed a self‐starting Kerr‐lens mode‐locked Ti:sapphire laser pumped synchronously by a mode‐locked, LBO‐doubled Nd:YAG laser. Using a home‐built beam‐pointing stabilizer, beam wander of the 532 nm pump is reduced by a factor of 25, thus enabling long term operation of TEM00nearly transform limited pulses with amplitude, repetition rate, and pulsewidth fluctuations comparable to or better than those of Ar‐pumped Ti:Al2O3lasers. Interferometric autocorrelation using second harmonic in reflection from GaAs yielded a pulse width of 30 fs, limited by the dispersion of wide bandwidth cavity optics which permit tunability from 0.7 to 1.0 &mgr;m.
