A diode-pumped composite-cavity electrooptically tuned microchip laser
has been constructed that tunes up to 30 GHz. The laser incorporates
a LiTaO3 electrooptic tuning element with acoustic damping to provide
linear voltage-to-frequency conversion with a tuning sensitivity of al
most-equal-to 14 MHz/V at modulation frequencies from dc to > 1.3 GHz.
