There is now a solution for practical real-time measurement of DPSS
pulse energies in the 30 - 50 kHz range. Laser Components presents the
mach 5 - the laser energy meter from Gentec-EO. The mach 5 exactly
measures the pulse-to-pulse energy. It counts all the pulses above a
certain defined energy threshold.
Major technological challenges made the latest development in the
measurement of single pulses of up to 130 kHz difficult: First, a
family of pyroelectric high-speed probes that can be used at
frequencies of more than 100.000 Hz had to be developed for energy
measurement purposes. At the same time, extremely fast, digital
electronics were developed that analyze each pulse in real time and
store this information just as quickly - approximately 4 million data
points are processed in just 40 seconds!
The energy meter determines energy, frequency, average power, and pulse
jitter in a single measurement. At the same time, it determines the
number of missing pulses or pulses below an energy threshold defined by
the user. With the included software it is possible to display the
measurement data in a strip chart, histogram, or statistics window. The
user's measurement profile can be stored for analysis at a later point
in time. For automated measurements use the automated "life test". The
measurement runs its course without the user's assistance.
