I asked Sue Witherspoon to set a software limit to IPG fiber amplifier set power so that it cannot exceed more than 5.0 W. IPG fiber amplifier has naximum 10 W power, but in order to protect PPLN crystal from high power damage by mistake, we did not want to have more than 5.0W of IR pump power to it. So if somebody type any number larger than 5.0 in the set power box, it doesn't accept. If we want to have more power for any reason we can ask Sue to change it back or we can have it in local mode.
