Warsash Scientific  offers the latest product from Spectrum Detector; the mach 5 100 kHz Digital Joulemeter, a pulsed laser energy measurement capable of 100,000 pps measurement with 12-bit accuracy. Mach 5 enables users to zero-in on each pulse of their 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. Data analysis and system control is provided by LabView software and drivers.

The mach 5 can be used for characterizing rep rate sources such as diode pumped Q-switched YAG/YLF lasers and ultra short pulse fiber lasers. It allows for product development, final test, life test, laser diagnostics, process development and process control.

The system is expected to find 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 allows it 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 energy range and enhances spatial uniformity.  

The probes include a detector-mounted thermistor that is used for temperature compensation increasing high accuracy and linearity at high average power levels.
