I planned to do a laser HCO this afternoon once the power outage was over. However the laser RF was not available due to an issue with the 1427 MHz amplifier. I turned lasers back on after was told the RF was ready but the RF frequency was not recovered from previous setting at 250MHz, so did a manual reset. Then did a partial HCO by checking the laser power and waveforms at different laser modes.
