Halite is a compact 1030 nm air-cooled femtosecond fibre laser from Fluence representing a new step forward in ultrafast laser design.

Fluence Halite Femtosecond Fibre Laser

Thanks to Fluence’s unique all-fibre technology, the Halite amplified oscillator provides high quality pulses as short as 170 fs with exceptional turn-key industrial grade performance and reliability. The SESAM (semiconductor saturable-absorber mirror) free oscillator design replaces degradable components found in similar ultrafast lasers to ensure excellent beam quality and unmatched long-term stability.

Standard Halite models offer 800 mW or 2 W average power, via high pulse energies up to 100 nJ at 20 MHz repetition rate. The soon to be released Halite HE will extend this up to 250 nJ at 20 MHz for 5 W average power. Green, UV and deep UV harmonic options are also available featuring exceptional conversion efficiency.

Halite is a cost-effective laser designed for applications such as multiphoton microscopy in both lab setups or integrated into commercial systems.

A demonstration of the impressive stability of Fluence’s lasers is shown the video below where a Halite is put through a vibration test.

Fluence OscillatorAnd the Fluence Oscillator which forms the backbone of the Halite and Jasper laser systems is also available by itself. This revolutionary all fibre femtosecond oscillator provides unrivalled tolerance to shocks, vibrations or temperature variations.

The oscillator features a special self-starting solution that ensures the laser mode-locks every time. This along with the long lifetime, compact size, and low power consumption make the Fluence Oscillator perfect for OEM applications.
