a. At 10 MHz and with the greatest pulse width achievable.
b. Typical maxima and are given for pulses that reach maximum output power. Some short duration pulses do
not reach maximum output power (see graph below) and therefore have reduced average output powers.
c. Relative to a beam axis normal to the plane of the front panel.
d. The major axis of the ellipse is vertically oriented when the bottom of the laser head is horizontal.
e. Pulse widths are adjustable in ~15 equal increments, from the minimum to the maximum specified widths.
f. The maximum supported edge transition time is 1 ms.
g. Applies to external triggering and internal triggering.
h. Trigger delay is measured between the SMA connector and the optical output at the lens.
