Recently, a significant stride has been made by the Shanghai Institute of Optics and Fine Mechanics, under the auspices of the Chinese Academy of Sciences, in partnership with Zhangjiang Lab. They have successfully advanced the development of a technical prototype for a Wide-Angle, Non-Collinear Optical Parametric Chirped Pulse Amplification (WNOPCPA) system.

The research team has ingeniously engineered an ultra-broadband seed source, boasting an impressive bandwidth of 500 nm, which spans wavelengths from 700 nm to 1200 nm. The driving force behind this innovation is a Yb:YAG industrial femtosecond laser, characterized by a full width at half maximum (FWHM) of 4 nm.

Leveraging the power of thin-disk compression and optical parametric amplification techniques, the team has achieved a remarkably flat spectral output. This breakthrough provides a robust and stable seed source for the WNOPCPA prototype, paving the way for future advancements in this field. The notable discoveries stemming from this research have been duly recognized and published in the esteemed journal, Optics Letters.
