Fig. 2: Photo-physical properties of BPAWR-SACM process.
From: Design of coherent wideband radiation process in a Nd3+-doped high entropy glass system
a Normalized emission spectrum (upper part) and normalized absorption spectrum (lower part) in the visible light range. The corresponding transition modes of Nd3+ ions are marked. The fitting spectrum represents the hypothesized emission spectrum with non-absorption. b Emission spectra at different measurement angles relative to the forward direction of the excitation light. The corresponding excited energy levels are marked in the figure. c Time-delay measurement between the residual pump pulse and the generated frequency-shifted radiation. d BPAWR-SACM signal power and conversion efficiency versus pump power of laser excitation at 874.9 nm (denoted as 874.9 nm Exc.) and 804.2 nm (denoted as 804.2 nm Exc.). e The suggested mechanism for the BPAWR-SACM process
