Large-Aperture Sensors
SANTA CLARA, Calif., Oct. 14, 2009 – Three new Quantum EnergyMax sensors from Coherent Inc. enable accurate measurement of laser pulse energies down to 20 pJ, as well as measurement of the average power of pulsed systems from the nanowatt to milliwatt levels, across a broad range of wavelengths.

The J-10SI-LE and J-10SI-HE are both silicon photodiode-based sensors with apertures of 10 mm and a spectral range of 325 to 900 nm, which measure down to 20 pJ and 200 pJ, respectively, at repetition rates of up to 10 kHz. The J 10GE-LE uses a 10-mm-aperture germanium photodiode to measure minimum pulse energies of 200 pJ over the 800 to 1700 nm spectral range, also at up to 10 kHz. The 10-mm large aperture can eliminate the need for an integrating sphere.

All three sensors are compatible with the company’s LabMax-TOP and LabMax-TOP with general-purpose interface bus meters. Quantitative measurement of picojoule pulses is difficult, but with these low-noise meters and the new sensors’ built in wavelength compensation feature, an absolute accuracy of better than 6% can be achieved. The sensors also deliver repetition rate linearity of less than ±1% error, from single-pulse measurement to 10 kHz.

The sensors are useful for a broad range of research, commercial and military applications involving low-power pulses. Examples include measurement of infrared pulsed lasers beyond 1064 nm, typically used for military targeting purposes, and measurement of kilohertz ultrafast oscillators and regenerative amplifier systems with outputs at the microjoule level or lower.

GLOSSARY
photonics
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
