Lake Oswego, OR - Spectrum Detector has become Gentec-eo USA, Inc., a leading manufacturer of detectors and instruments for optical and laser power and energy measurements, introduced mach 5, a breakthrough 100 kHz digital joulemeter that answers the demand for real-time, pulse-to-pulse energy measurement of high rep rate laser sources. Capable of better than 100,000 pps measurement with 12-bit accuracy, mach 5 enables users, for the first time ever, to zero-in on each and every pulse of their ultrafast pulsed lasers. The mach 5 captures and stores up to 4 million pulses (40 seconds of data at maximum rep rate) and on command dumps them to the user's PC via a full speed USB 2.0 interface. Comprehensive data analysis and system control is provided by full-featured LabView software and drivers.

The mach 5 is optimal for characterizing such high rep rate sources as diode pumped Q-switched YAG/YLF lasers and ultra short pulse fiber lasers. It is ideal for product development, final test, life test, laser diagnostics, process development and process control. The system is expected to find wide use in applications relating to solar cell processing, semiconductor via hole drilling, wafer scribing and micromachining. The system's compact detector probe and small electronics package also makes it easy to integrate into industrial laser systems for on-board diagnostics and control.

The mach 5 is available with two specially-designed fast joulemeter probes: the M5-SJ high-sensitivity silicon probe for measurement from nJ to uJ and 0.19 to 1.1 um, and the M5-PJ Pyroelectric for measurement from uJ to mJ and 0.25 to 15 um. Key to these probes is a small integrating sphere with a 6 mm input aperture that extends the useful energy range and enhances spatial uniformity. In addition the probes include a detector-mounted thermistor that is used for temperature compensation providing high accuracy and linearity at high average power levels. The complete system – probe and electronics – is accurate to better than 4% and is NIST traceable.

Equally innovative is the system's full-featured LabView software, which sets new standards in joulemeter data analysis and system control. An "Instrument Controls" display enables fast set up of range, trigger level, trigger source and delay. The user can also select an auto set function to automatically determine appropriate settings. The "Live Mode" display is ideal for quick measurements and laser set up. The "Data Strip Chart" display provides a quick graphical look at the pulse batch collected. A "Data Histogram" display provides best-fit Gaussian curve full stats. The "Statistics" display provides complete statistics on the data collected including min, max, SD, spread, missing pulses and more. An "FFT" (Fast Fourier Transform) display shows amplitude spectrum and phase. It provides the ability to analyze the data batch for any periodic phenomena that might have an effect on laser performance. Lastly, the "Life Test" is used to set up mach 5 to conduct life or periodic pulse energy test based on user specified parameters including start and stop time, number of pulses, and test interval.
