Gentec-EO – Laser Power Meter & Laser Energy Meters

TECHNICAL SHEET Technical Drawings Energy Detectors Section

The 50 mm aperture is designed for large beams and high energy laser beams. Beams that are too intense for the QE25 can be expanded onto the large aperture. It has one of the best damage thresholds of any energy detector of its class.

The short pulse QE50-SP-MT gives you repetition rates up to 4000 Hz (can be read with the SOLO 2 up to 3000 Hz) with pulse lengths up to 10 µs. The short pulse QE50-SP-MB gives you repetition rates up to 500 Hz with pulse lengths up to 225 µs. The long pulse QE50-LP-MB is for users who need more pulse width than repetition rate. Also available on special orders, the QE50-ELP-MB for measurement of Extra Long Pulses up to 7 msec, custom-tuned for repetition rate, sensitivity, and pulse width.

The QE50 with heatsink (H) is good for higher average powers up to 20 W.

To extend the performance of the QE50 to higher pulse energies you can select our QED attenuator.
