Ophir-Spiricon pyroelectric detectors measure pulse energies up to 40 J

The PE25BF-DIF and PE100BF-DIF are pyroelectric detectors for repetitive pulses. The PE25BF-DIF has a fast broadband absorber that measures from 193 nm to 2.2 μm at pulse rates to 150 Hz; pulse energies are measured up to 10 J. The PE100BF-DIF measures from 193 nm to 2.0 μm at pulse rates to 40 Hz; pulse energies are measured to 40 J. They use a single, removable diffuser to cover UV, visible, and mid-infrared wavelengths.

PRESS RELEASE

Ophir-Spiricon Expands Line of Pyroelectric Laser Energy Sensors with Highest Damage Threshold and Pulse Energies, and Broadest Range of Wavelengths Logan, UT - Ophir-Spiricon, the global leader in precision laser measurement equipment, today announced the PE25BF-DIF and PE100BF-DIF, the newest members of the company's line of pyroelectric detectors for repetitive pulses. These energy sensors provide the highest damage threshold, highest pulse energies, and widest spectral range in the industry. The PE25BF-DIF has a fast broadband absorber that accurately measures from 193nm to 2.2µm at pulse rates to 150Hz; pulse energies are measured up to 10J. The PE100BF-DIF measures from 193nm to 2.0µm at pulse rates to 40Hz; pulse energies are measured to 40J. While most high damage threshold detectors require multiple diffusers to cover the spectral range, the PE25BF-DIF and PE100BF-DIF use a single, removable diffuser to cover UV, Visible, and Mid-IR wavelengths. This results in an accurate and flexible system that handles a wide range of measurement requirements. The sensors work with most types of pulsed lasers, from short to long pulse, and from low to high energy. The PE25BF-DIF Pyroelectric Detector is designed for medium size pulsed lasers with high energy densities - including YAG, Holmium, and Erbium lasers - that require high damage thresholds. It features a 25mm aperture and metallic coating that measures repetition rates to 150Hz. The sensor measures pulse widths of up to 5ms, five times that of the nearest competitor. The detector's BF coating provides the highest damage threshold in the industry for UV wavelengths and is among the highest for all others, ranging from 2 J/cm2 at <100ns to 40 J/cm2 at 2ms. For lower energy densities, the PE25BF sensor is available without a diffuser. The PE100BF-DIF Pyroelectric Detector is designed for very large pulsed lasers with high energy densities that require high damage thresholds. It features a 85mm aperture and metallic coating that measures repetition rates to 40Hz. The sensor measures pulse widths of up to 10ms, ten+ times that of the nearest competitor. The detector's BF coating provides the highest damage threshold in the industry for UV wavelengths, 3 J/cm2 at <10ns. "The PE line of energy sensors was created for repetitive pulse lasers with high energies and high energy densities," stated Ephraim Greenfield, VP Engineering, Laser Measurement Group, Ophir-Spiricon Inc. "The patented design combines highly accurate measurement of average power using a thermal head with measurements of relative pulse energy using a photodiode that provides energy per pulse. The combination allows the sensors to measure powers and energies only a thermal head would be able to measure but for repetitive pulses at repetition rates never before seen." Both the PE25BF-DIF and PE100BF-DIF provide data about pulse energy, average power, frequency, minimum and maximum values, missing pulses, time jitter, and standard deviation. Up to 50,000 points of data can be stored. The display of pulse energies can be either numerical or graphical using one of Ophir's smart displays or PC interfaces, including the Orion PE, Nova, Nova II, Vega, LaserStar, USBI, Pulsar, and Quasar. Each display features a "Smart Connector" interface that automatically configures and calibrates the display when plugged into one of the company's measurement heads.
