Abstract
The bandwidth of a frequency-shifted feedback Ti:sapphire laser is compressed through compensation for the shifted frequency inside the laser cavity by means of dual acousto-optic tunable filters (AOTFs) without the employment of an etalon. The laser wavelength can be tuned electronically in a 167-nm range by changes in the rf input to the two AOTFs. Wide-range tunability is achieved without mechanical adjustment or the addition of dispersive elements.
