Where to Buy Pulse Characterization Instruments

Our compact ultrafast autocorrelator is used to characterize ultrafast laser pulses originating from Ti:sapphire and Yb:doped lasers. Featuring a built-in two-photon absorption (TPA) detector, this autocorrelator is ideal for measuring ultrafast femtosecond and picosecond laser pulses at wavelengths from 700 to 1100 nm. The highly sensitive TPA detector allows for measurements of ultrafast laser pulses with high sensitivity by eliminating the need for angle tuning of the SHG nonlinear crystal.

The FROGscan is an instrument for the full characterization of ultrafast laser pulses. A single device can use a variety of spectrometers that can provide wide wavelength range, high spectral resolution and over 75 dB of dynamic range. Wavelengths from 450 nm to >4000 nm and pulse durations from 12 fs to 10's of picoseconds are within the reach of a single system. A zero-dispersion design allows pulses <5 fs to be measured. The FROGscan is the instrument that can measure the most complex pulses.

The FSAC benchtop interferometric autocorrelator manufactured by Thorlabs is designed to characterize ultrafast pulse durations from 10 – 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 chirped mirrors, low GDD mirrors/beamsplitters, and dispersion compensating fiber.

The Chirpscan technique is a perfect extension to a Dazzler for pulse compression optimization.

The large scanning range of the Dazzler allows to measure pulses with large time–bandwidth products, thus making it the ideal tool for the alignment and optimization of a compressor.

Specially developed to characterize the output of Fastlite high-flux MIR OPCPA sources, the Frozzer can measure pulses from 3 optical cycles to 5 ps between 1 and 9 μm. It is thus perfectly adaped to the temporal characterization of Yb, Er, or Tm-doped systems as well as signal, idler and DFG outputs of OPA and OPCPA systems.

Femto Easy offers different kinds of devices for the characterization of ultrashort light pulses:

• Single-shot and scanning autocorrelators are easy tools for measuring pulse durations.
• FROG devices allow for full pulse characterization. They are also available in single-shot and scanning versions.

All devices are optimized for easy installation and handling.

APE offers a range of products for pulse characterization in the picosecond and femtosecond domain:

• autocorrelators
• FROG
• SPIDER
• spectrometers

The Blueback advanced ultrashort laser pulse characterization device is a real-time ulstrashort laser pulse characterization device specifically engineered to provide a high-resolution measurement for ultrafast oscillators and amplifiers. It is an essential piece of equipment for everyone who depends on accurate information about properties of their ultra-short pulses. With Fluence Blueback you get more than just a single result. You can watch your pulse evolving in real time.

The d-cycle is a compact system for the comprehensive characterization (full electric field) of ultrafast laser pulses. Four different d-cycle models support optical spectra corresponding to pulse durations from 2.5 to 200 fs and work with pulse repetition rates ranging from 10Hz to hundreds of kHz or even MHz.

Coupling the laser beam into the d-cycle is easily achieved in less than five minutes, and a full measurement (including retrieval) usually takes less than 10 s. The intuitiveness of the d-cycle trace provides instant visual feedback for the optimisation of your source.

The d-shot is a single shot version for ultrafast pulses characterization. d-shot is a very practical tool for real-time alignment and optimisation of your compressor or pulse shaper.

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). For example, photodetectors with rise time 10 ps and bandwidth 30 GHz in combination with 50 GHz sampling oscilloscope can be successfully 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.
