Measuring Ultrashort Pulses with IQFROG - Intensity and Phase Measurements for a Wide Range of Pulse Lengths

04 Sep 2017

The IQFROG can be used to measure the intensity and phase of optical pulses in

both spectral and temporal domains, giving a complete pulse characterisation. It is

based on the principle of frequency-resolved optical gating (spectrally resolved SHG

autocorrelation) which allows sub-picosecond resolution since it is not limited by the

response time of the detector.

Thanks to its long delay arm and high-resolution spectrometer, the IQFROG is

able to measure a wide range of optical pulses lengths; from 300fs, up to 50ps for

chirped pulses. The user friendly software recovers all the characteristics of the pulse,

including pulse shape, spectrum, chirp and group delay.

The IQFROG is available in 1.0μm and 1.5μm wavelength versions. The 1μm version

is an ideal tool for seed laser pulse characterisation in chirped pulse amplification

(CPA), while the 1.5μm version is suitable for C & L band telecom applications. In

both versions a connectorised fibre input makes coupling of the beam easy and

eliminates need for manual alignment.
