Mode-hop suppression of Littrow grating-tuned lasers: erratum

A recent paper [Appl. Opt. 32, 269-274 (1993)) contained an analysis of the conditions required to suppress mode hops when one is tuning a Littrow grating-loaded laser cavity. Although the model was correct, an algebraic mistake led to a wrong conclusion. The corrected results are given and tend to recommend a previously investigated configuration.
