The helixx is a turn-key femtosecond laser with tuning range between 720 and 920 nm. It delivers over 2.3 W of average power in pulses below 50 fs, with a 250 MHz repetition rate. The innovative design combines a compact, hermetically sealed, vibration-resistant laser head that incorporates the Ti:Sapphire oscillator and pump laser, with a full-feature control unit. The control unit houses the field replaceable pump diodes, isolating temperature effects from the helixx laser head, and provides intelligent control that both monitors and maintains laser performance.
The helixx is particularly ideal for two-photon microscopy. The repetition rate of 250 MHz significantly lessens photobleaching and phototoxicity, thus reducing damage to the cells and minimizes the emission dead times of typical fluorophores.
