==780 Laser Notes==
TA is a 3 micron chip 1W 780 nm from Eagleyard Photonics. TPA-0780-01000-3006
There should be about 2 mW of power going into the TA. 5/15/14, increased 780 Laser current from 43 mA to 65 mA and adjusted the waveplate to continue sending 2 mW to the TA and the rest of the power to a fiber. Locked the waveplate at the right position--do not adjust without decreasing laser current. ▼
Specified maximum rating is 3 amps of input current when seeded, but should be able to output 1W with 2 amps.
There should be about 2 mW of power going into the TA, although 5-10 mW should be fine is output power isn't at 1W with the current around 2 amps.
'''5/19/14''' Having difficulty seeing 633 nm generation from the 780 TA beam, but realized that the TA can actually take more current than we previously thought. Increased current to 2 amps and adjusted waveplate to give about 3.3 mW of seed power. Current for the seed is still at 65 mA. Output from the TA increased from about 500 mW to 1000 mW.
