Abstract
A scannable dye laser is provided with an integral wavemeter under computer control. The wavemeter has improved fine and coarse readout components. Incremental laser scans are precisely linked together to provide long, continuous frequency scans. The fine readout of the wavemeter provides a means for accurately piecing together the incremental scans.
