ECDL Tuning
7/14/15
Tuned a 785nm laser by keeping current fixed at 68.5mA and ramping the grating piezo from 0 to 150V. Got a pretty decent plot of frequency vs piezo voltage with clear mode hops. Decreasing the voltage from 150V to 0V yielded a messier plot with more random mode hops. In all, the laser tunes with a rate of about .16 GHz/V.
