IQFROG For Measuring Ultrashort Pulses

02 Jun 2021

LASER COMPONENTS is pleased to introduce the high spectral resolution IQFROG, available in 1.0μm and 1.5μm wavelength versions which allows the measurement for the second harmonic spectrum of a pulse.  The resolution of the spectral measurement often limits the broadest pulse width that a pulse analyser can measure.

The IQFROG has a built-in high-resolution spectrometer to enable measurement of transform-limited pulses of up to 10ps width, or broader if the pulse has a frequency chirp.  The system uses a long mechanical translation stage to provide up to 200ps of scan range to allow autocorrelation measurement of up to 50ps long pulses.  It is one of the few pulse analysers on the market which can measure such broad picosecond pulses, as well as short pulses down to 300fs width.  In comparison the competitive SPIDER technique is limited in the ability to measure pulses broader than 1ps.

The IQFROG can scan and save autocorrelation traces, even if the pulse is too broad (with a very narrow spectral width) or is unsuitable for FROG recovery.  The IQFROG can also be used as an autocorrelator.

The connectorised input makes coupling of the beam easy and fast by eliminating the need to align the beam into the unit manually.  The IQFROG is by far the most easy-to-use optical pulse analyser on the market.  The mechanical control, alignment and tuning is controlled by the software, no more need to align manually.
