On the Cover: Ultra-broadband near-infrared NOPAs based on the nonlinear crystals BiBO and YCOB
The image on the cover of High Power Laser Science and Engineering Volume 8, Issue 3, evaluates and demonstrates ultra-broadband near-infrared noncollinear optical parametric amplification in two nonlinear crystals, bismuth borate (BiBO) and yttrium calcium oxyborate (YCOB), which are not commonly used for this application. Provided by M. Galletti et al., researchers from Universidade de Lisboa, Harwell Science and Innovation Campus and INFN-LNF, the image is based on the research presented in their article, "Ultra-broadband near-infrared NOPAs based on the nonlinear crystals BiBO and YCOB", High Power Laser Science and Engineering 8(3) 03000e29, doi 10.1017/hpl.2020.27.
