QuixX® Picosecond-pulsed & CW Diode Lasers

Universal diode lasers with pulsed and continuous wave operation


QuixX® diode lasers offer picosecond pulsed operation as well as continuous wave operation with modulation capability. The QuixX offers full intensity modulation and gating by external analogue and digital modulation signals at high frequencies in both pulsed and CW modes. During pulsed operation, the pulse-shape can be adjusted in shape, height and repetition-rate by software control. In “low-power”-mode the laser does produce Gaussian shaped pulses without any aftershoot / shoulder. In “high-power”-mode a higher peak and average power is achieved compromising some aftershoot. Additionally, in the “expert”-mode, any pulse-shape between low-power and high-power mode can be adjusted. The built-in software programmable function generator can generate frequencies from 1 Hz to 100MHz with very low jitter, just like an external high-end function generator.

For easy synchronisation of external devices like cameras, fast detectors or sensors the laser has an integrated delay generator for its SYNC output signal. The Pulse-to-SYNC signal can be delayed by up to 28 nanoseconds with 10 picoseconds in resolution. This function can also be used to daisy-chain multiple QuixX lasers in Master/Slave setups. Due to Omicron´s proprietary focal shaping technology, the natural astigmatism of laser diodes is eliminated, producing a high quality laser beam with perfect focusability. In free-space application the laser can be focused near to the diffraction limit resulting in a round, Gaussian focal point. This also enables very high fibre coupling efficiency into single-mode fibres. Extraordinary synchronisation features with high resolution delay generator, internal frequency generation and user-selectable input and output signals make these lasers the most versatile laser diode modules for industrial, biotech and scientific use.
