1) Please refer to the power and energy vs. pulse repetition rate curves for typical values. Switching time between different repetition rates and burst number is <20ms.
2) 1030 power is constant at all pulse durations; 515nm power is guaranteed only at min pulse duration and will decrease when stretching the pulse duration.
3) Attenuation can be controlled by a few different methods:
a) by PC user interface,
b) by CAN register,
c) by analog input (0-1V, rise time <1μs). Beam quality specifications are maintained down to 10% power level for 1030nm output and 3% for 515nm output.
4) Defined as the worst case ellipticity along the z-scan (± 5 × L_Rayleigh) of the beam.
5) Measured during 8 h operation starting 30 minutes after warm-up. Environmental temperature stability within ± 1 °C.
6) Measured with integration time of 1 s at the same conditions as (5).
7) Measured within 10 s time interval for at least 1000 pulses.
8) Coldplate is provided attached to the laser head of the laser. A water chiller is not provided. Requirements for the chiller are >1L/min flow rate and 25-33 °C water temperature.
