Selfmodelocked diodepumped Cr:LiSAF laser is ultrafast and compact

An allsolidstate selfmodelocked Cr:LiSAF laser pumped by a single 250mW semiconductor laser produces almostbandwidthlimited broadly tunable 97fs output pulses. Researchers at the University of Strathclyde (Glasgow, Scotland) used the Kerrlens effect in the laser cavity to obtain selfmodelocking, which was initiated with a regeneratively driven acoustooptic modulator and was observed over a period of several days without any adjustment to the cavity or the pum¥optics.
