Average power measurement of pulsed sources from nW to mW level signal-to-noise characteristics
Measures every pulse to 10,000 Hz
Accurate spectral compensation (325 nm to 900 nm / 800nm to 1700 nm)
New Large Aperture Sensors for Very Low Energy Laser Pulses.
These Quantum EnergyMax sensors enable accurate measurement of laser pulse energies down to 20 pJ, as well as the average power of pulsed systems from the nanowatt to milliwatt level, across a broad range of wavelengths. Specifically, 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 nm 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 utilizes a 10 mm aperture germanium photodiode to measure minimum pulse energies of 200 pJ over the 800 nm to 1700 nm spectral range, also at up to 10 kHz. The 10 mm aperture is the largest currently available on the market for detectors of this sensitivity, and can often eliminate the need to utilize an integrating sphere.
All three Quantum EnergyMax sensors are compatible with the Coherent LabMax-TOP and LabMax-TOP with GPIB meters. Quantitative measurement of picojoule pulses is notoriously difficult, but with these low noise meters and the sensors’ built in wavelength compensation feature, an absolute accuracy of better than 6% can be achieved. Quantum EnergyMax sensors also deliver an excellent repetition rate linearity of less than ±1% error, from single pulse
measurement to 10 kHz.
Quantum EnergyMax 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. Other examples are measurement of kHz ultrafast oscillators and regenerative amplifier systems with outputs at the microjoule level or lower.
