It was the best of lasing. It was the worst of lasing. It was the best of shipments (although still bad). It was the worst of shipments. It was the season of single mode. It was the season of no modes. TCS has now received back the lasers that were sent to Access for repairs. Unfortunately the first shipment containing Lasy-50 20510-208160 and RF50 208160-20510 was sent to Caltech (an oversight in shipping) and then to Hanford. It was worse for the wear and the RF driver was busted, it was blowing fuses. Using the RF50 210040 to drive the laser proved more fruitful, while RF50 208160-20510 will be sent back to Access for repairs. Here are the laser/RF driver pairs and their outputs (running at 99% duty cycle) as tested:
| Laser | RF Driver | Watts | Notes |
|---|---|---|---|
| 20510-208160 | 210040 | ~53 | RF50 208160-20510 Broken |
| 20708-208100 | 20708-208100 | ~53 | RF50 water inlets bent |
| 210020-20710 | 20710-210020 | ~52 | RF50 broken water inlet, replaced. Break in wire sheath, fixed. |
Attached are some of the photos from the process, including the beam on an IR card.
