30 Jan 2017 With the innovative “QuixX” laser series, the German laser expert Omicron provides compact laser modules with fully integrated driver electronics, high precision temperature regulation and beam shaping optics. The laser is able to emit ultrashort pulses down to 50 picoseconds with user-adjustable pulse shape as well as continuous wave (CW) in combination with fast analogue modulation and digital gating / shuttering in the megahertz range.
In picosecond operation, QuixX offers a “narrow-pulse” mode with pure Gaussian pulse shape. In “wide-pulse” mode, the laser is able to emit longer pulses up to 1 nanosecond and higher peak powers. For even more flexibility, a so called “expert mode” allows the user to adjust the pulse-shape to the exact needs of the application. Both CW and picosecond operation offer the possibility for laser intensity and peak power modulation with up to 3 megahertz. Furthermore the modules have got an electronic shutter function which can switch the emission in full on/off regime at a bandwidth of more than 150 kilohertz. In pulsed mode the repetition rate can either be triggered by an external synchronization signal, or it can be generated by the internal, programmable frequency generator with up to 100 megahertz. The delay generator for the SYNC output can be used to synchronize external devices with up to 28 nanoseconds pulse-to-sync delay and 10 picoseconds resolution. The QuixX systems are available with up to 500 milliwatt optical output power in single-mode and wavelengths between 375 and 2090 nanometer. The light output can be either free-space or fibre-coupled with high efficiency.
The QuixX modules can be integrated into new or already existing applications via its RS-232 and USB-2.0 interfaces in an optimal way. For easy use, a comfortable control software is included in delivery. Typical applications are time-resolved single photon counting, spectroscopy, fluorescence microscopy including FRAP, TIRF, FLIM and STED as well as the use as seed or pump laser for fibre lasers and MOPA systems. |
