Key Facts:

Picosecond & CW mode
The laser is able to emit ultrashort pulses down to 50 picoseconds as well as continuous wave (CW). Low pulse-to-pulse jitter <2ps in picosecond mode as well as high stability and low noise emission in CW mode is assured by latest high-end quality electronics.

User adjustable pulse-shape
In picosecond mode the pulse-shape can be adjusted in shape, height and repetition-rate by software control comfortably. 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. In the additional “expert”-mode, any pulse-shape between low-power and high-power mode can be adjusted.

Arbitrary frequency Generator
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.

Programmable delay Generator
For easy synchronization 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.

Modulation & gating capability
In both picosecond and CW operation, the QuixX offers full intensity modulation and gating by external analog and digital modulation signals at high frequencies.

Highest fibre coupling Efficiency
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.

Each QuixX diode laser modules is delivered with the Omicron Control Center (OCC) – Laser Control Software.
The software can control multiple lasers and offers a Master section which controls all lasers in parallel. The OCC can be used for daily use or just for configuring the laser for computer independent operation once.
