Unique femtosecond oscillator, 250 MHz repetition rate: helixx

19 Dec 2018

The new Laser Quantum femtosecond oscillator, the helixx, is an innovative plug and play laser with a unique 250 MHz repetition rate, designed for life science applications.

The helixx system is tuneable between 720 nm and 920 nm to meet the requirements of the user and delivers an average output power of >2.3 W in short pulse durations of ~50 fs. A range of optional features are also available to meet wide-ranging needs: pulse train monitoring, repetition rate control, active locking and modulation of pump power for phase stabilisation, where required.

The laser head incorporates both a Ti:Sapphire oscillator and pump laser, and its field replaceable pump diodes are contained within the full-feature control unit, minimising the thermal load on the laser head for outstanding stability.

The helixx is well suited to two-photon microscopy, as its 250 MHz repetition rate significantly lessens the effects of photobleaching and phototoxicity, minimising cell damage and emission dead times of typical fluorophores for optimal imaging results. Laser Quantum prides itself on robust and reliable lasers with long lifetimes and exceptional performance, and offers remote diagnostics and support via proprietary connection software.
