'''7/3/14''' Threshold test seemed off yesterday and was very off today. It took about 26 mA today to get to 100 μW and the laser was very multimode. Adjusting the grating position ultimately resolved the problem. The current reading on the driver is sometimes fluctuating, usually just by .1 mA, but sometimes by up to 5 mA. This doesn't seem to be causing any problems right now, but it is unclear why this is happening.
==1555 Laser Notes==
Diode is a QPhotonics QLD-1550-40S-AR. See specs [https://wiki.physics.wisc.edu/yavuz/images/8/85/1555_diode_specs.PNG here] and datasheet [https://wiki.physics.wisc.edu/yavuz/images/b/b5/1555_diode_data_sheet.pdf here]
