There is now a solution for practical real-time measurement of DPSS pulse energies in the 30-50 kHz range: the mach 5!
The requirement for the development of the mach 5, which has been met in its entirety, was the exact measurement of pulse-to-pulse energy; and each pulse had to be tested. None of the pulses above a certain defined energy threshold should be missing.
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 have to be processed in just 40 seconds!
Why else should you use the mach 5?
- Determine energy, frequency, average power, and pulse jitter in a single measurement.
- Determine the number of missing pulses or pulses below an energy threshold defined by you, for example.
- Display your measurement data in a strip chart, histogram, or statistics window using the mach 5 software.
- Store your own measurement profile for analysis at a later point in time.
- Use an automated “life test” for your laser – the measurement runs its course without your assistance!
