Ultrafast fiber laser Introduction

The Y-Fi™ laser family is a unique, world-leading, series of high average power, multi-MHz repetition-rate ultrafast fiber lasers. Y-Fi™ products are based on a briefcase-size, rugged platform, are engineered for hands-free operation, and are distinguished from the competition by their ultrashort pulse duration for µJ-level pulsed fiber lasers: 80-200 fs, and even shorter using an integrated OPA.

The Y-Fi™ operates at 1035 nm, with average power up to 35W. Different configurations allow for different maximum pulse energy, and a series of integrated options allow for broad spectral coverage: the Y-Fi™ OPA extends operation to 4 µm, while frequency conversion opens up the visible-VUV wavelength regions.
