Solid state lasers are demanding independent control in the gain media and cavity loss to achieve ultra short laser pulses using passive mode‐locking. Recently, laser mode‐locking is achieved with a MBE structure with multiple quantum wells, designed to achieve two functions; Bragg mirror and changes in absorption to control the cavity dynamics. The use of an AlGaAs/AlAs Bragg mirror with a 15 nm GaAs saturable absorber used in a Cr:LiSAF tuneable laser proved to be effective to produce femtosecond pulses. The use of saturable absorbers thus far is a trial and error procedure that is changing due to the correlation with more predictive procedures. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
