1. Rise time for pulsed conditions, measured at 25 Hz and 50% DC
2. Defined as the time required for laser stabilization (time to establish LD and NLC operation temperature and crystal thermal lens). In pulsed mode, the warm up time only affects the first pulses.
3. Within the temperature range, optical power could vary ±10%, to be compensated from the monitor photodiode signal through PID.
For higher temperatures, laser head should be mounted on a cooled surface with a capacity to remove 60 W waste heat at max. housing
