Before You Buy: Learn About Pulse Duration Measurement Devices
Measuring the durations of nanosecond pulses can be done with fast photodiodes. However, for ultrashort pulses in the picosecond or femtosecond range, advanced instruments like autocorrelators, FROG, SPIDER, or streak cameras are required.

Ultrafast photodetectors from ALPHALAS in combination with high-speed oscilloscopes are the best alternative for measurement of optical waveforms with spectral coverage from 170 to 2600 nm (VUV to IR) and picosecond pulse duration. For example, photodetectors with rise time 10 ps and bandwidth 30 GHz, combined with a 50-GHz sampling oscilloscope, can be used to measure optical pulse widths down to 10 ps using deconvolution.
Configurations of the photodetectors include free-space, fiber receptacle or SM-fiber-pigtailed options and have compact metal housings for noise immunity. The UV-extended versions of the Si photodiodes are the only commercial products that cover the spectral range from 170 to 1100 nm with a rise time < 50 ps. For maximum flexibility, most models are not internally terminated. A 50 Ohm external termination supports the specified highest speed operation.
Femto Easy offers two different types of very compact and handy autocorrelators for ultrashort pulse characterization:
The ROC autocorrelator is a single-shot autocorrelator, thus it needs only a single pulse to measure its duration. It is very compact and extremely easy to use. It covers a wide range of pulse energies from a few hundred picojoules to a few millijoules, and durations from 5 fs to 10 ps.
The MS-ROC autocorrelator is a multi-shot autocorrelator. It uses a particularly fast optical delay line to scan the delay, minimizing the measurement time. It can measure pulses with energies as low as 50 pJ, and with its fine-scan mode for durations even below 50 fs.
APE autocorrelators are used to measure the pulse duration of femtosecond and picosecond laser systems. The technology is based on either second harmonic generation (SHG) detection or two-photon absorption (TPA) detection principle.
The FSAC benchtop interferometric autocorrelator manufactured by Thorlabs is designed to characterize ultrafast pulse durations from 15 – 1,000 fs in the 650 – 1100 nm range. This autocorrelator for use with femtosecond lasers compliments our ultrafast family of lasers, amplifiers, and specialized optics, including nonlinear crystals, chirped mirrors, low GDD mirrors/beamsplitters, and dispersion compensating fiber.
The orchestra™ FROG (Frequency-Resolved Optical Gating) combines SHG (second harmonic generation) and TG (transient grating) FROG in one device with total spectral range from 200 nm to 2 μm (up to 3.4 μm optional). It comes with user-friendly software for acquisition and phase retrieval.
