The Arex™ A20-X6X shows similar behavior for all other pulse profiles, within
the same operating conditions. For each pulse profile there is a maximum
allowed input frequency (fmax) and a Transition Frequency (fT) (refer to your
device Test Report for details about your specific laser). As illustrated in follow-
ing picture, below the transition frequency, the pulse peak power and energy will
r
emain constant for all pulse profiles.
Figure 2: Typical average power (dash line) and peak power (solid line) dependence on the
frequency for the typical pulse profile available - 4ns to 250ns. Note that, typically, fT
=fmax=500kHz for 4ns Pulse Profile
