Autocorrelators and Pulsediagnostic from DYNEOS AG

The Mini TPA and Mini PD are compact interferometer-based autocorrelators for measuring the pulse duration of fs and ps lasers with any frequency >500Hz. Both are available for different wavelength ranges, easy to adjust and operate. The pulseCheck autocorrelator is a versatile, flexible device for measuring the pulse duration of various fs- and ps lasers over a very wide wavelength range. The new pulseCheck Type 2 enables high-contrast measurements on a logarithmic scale for the temporal characterization of intense pulses including pre-pulses and sockets. The Carpe is the first commercially available autocorrelator for the use with laser microscopes. Based on the proven and patented SPIDER technology, the Spider family, consisting of the FC Spider for precise temporal characterization of ultrashort pulses, the Compact LX Spider as a variant for the Ti:Sa-Laser spectrum and the Spider IR for short pulses with a central wavelength of 1μm, APE presents new precision measuring instruments. The PulseSelect was developed for the special requirements of fs and ps laser technology. Low dispersion and acousto-optical selection minimise pulse distortion and enable a high contrast ratio. FemtoControl is a compact, motorized device for dispersion control of ultrashort pulses. The HarmoniXX family is a series of frequency multipliers for ultrashort pulse lasers, especially for Ti: Sa systems, but also for other wavelength ranges.

The GECO autocorrelator is based on noncollinear second harmonic generation in a nonlinear crystal, producing intensity autocorrelation trace directly related to the input beam pulse duration. One arm of the fundamental pulse is delayed by means of a magnetic linear positioning stage, providing fast, reliable motion with <0.15 fs resolution. GECO can acquire a full intensity autocorrelation trace of 10fs to 20ps pulses and covers the full 500nm to 2000nm wavelength range. GECO comes with a convenient pulse-analysis software, providing straightforward pulse duration measurements. A computer is integrated inside the autocorrelator thus communications are handled via TCP/IP protocol which ensures a simple trouble-free installation. Software and hardware is also capable of generating FROG traces, provided that an external spectrometer is connected to the fiber coupler. Software API's are available for custom user adaptations. TiPA is an invaluable tool for alignment of ultrashort pulse laser systems based on the chirped pulse amplification technique. Its unique design allows monitoring and measuring of the pulse duration as well as the pulse front tilt in both vertical and horizontal planes. TiPA is a straightforward and accurate direct pulse‑front tilt measurement tool. Operation of TiPA is based on non‑collinear second harmonic (SH) generation, where the spatial distribution of the SH beam contains information on the temporal shape of the fundamental pulse. TiPA comes with a user friendly software package, which provides on-line monitoring of incoming pulse properties.
