High Speed MHz Power Sensor

Blink-HS: high speed laser power and energy sensor head: 500 MSamples/s

LaserPoint's BLINK-HS laser sensors (and associated meter) are based on a proprietary technology on thermopile design that makes this product the fastest laser power and energy sensor currently available. This technology allows combining the high response speed of a photodiode with the broadband and high power operation of a thermopile.

Laser applications requiring high speed measurements can take advantage of the sub-microsecond response time. This BLINK-HS feature allows
- measuring the energy of each pulse emitted by laser sources with
- repetition rates up to 1 MHz,
- pulse durations down to femtoseconds (fs) and
- average power up to 20W,
characteristics that cannot be present all together in pyroelectric, thermopile or photodiode sensors. Moreover, its high damage threshold and efficient water cooling allow withstanding energies up to 10mJ.

Key features of the Blink-HS high speed laser power and energy sensor head:
- 20 W max. laser power measurement
- 10 mJ max. laser energy measurement
- measurement active area: 14x14 mm
- 250-1100nm and 10.6 um
- 500 MSamples/s sampling rate

BLINKHS can be deployed by laser manufactures to detect fast instabilities in laser sources as well as by system integrators to monitor fast processes in production lines. Combining all advantages present in photodiodes, pyroelectric and thermal detectors, BLINKHS is a very versatile product, suited to measure most of the laser sources commercially available, from ultrashort pulse (ultrafast) to CW lasers. High speed electronics is also available with a sampling rate up to 500 Msample/s to provide a precise energy measurement of each single ultrashort pulse.
