Electronically tuned Ti:sapphire laser

We have applied a birefringent acousto-optic crystal for wavelength tuning of a Ti:sapphire laser. A continuous-tuning range of 12 nm, which was limited by wavelength-dependent angle deviation of the beam def lection in the crystal, was extended to over 100 nm by optical correction. Fast and random access of lasing wavelengths by direct electronic tuning was demonstrated at a pulsed operation of 10 Hz.
