PRESS RELEASE

Fidelity

Coherent has launched its Fidelity laser, a sealed-box fibre laser that delivers short (<70fs) pulse widths and high (>2W) average power at 1,055nm. The laser is an economical oscillator that is air-cooled with a footprint of 318 x 318mm, and produces a high quality (M2<1.2) output beam. This makes it suitable for applications in multiphoton imaging, terahertz generation, and material research.

Fidelity’s high repetition rate (64MHz) enables fast data acquisition. It also includes an integrated and electronically adjustable pre-chirp adjustment to fine-tune or minimise the pulse width at the experiment itself.

Fidelity is suitable for most scientific applications such as ultrafast spectroscopy and supercontinuum generation. Compared to titanium:sapphire-based systems, Fidelity’s combination of very short pulses with high power at long wavelengths is a particular advantage in deep in-vivo bio-imaging applications such as optogenetics. The combination of Fidelity with Coherent’s Chameleon lasers enables advanced neuroscience experiments requiring simultaneous imaging, photo-activation and action potential detection in live animal brains, both with standard and multi-point modalities.
