Functional Unit Design of Deep‐UV NLO Crystals With Short Phase‐Matching and Large SHG Response
Xinjiang Technical Institute of Physics & Chemistry · University of Chinese Academy of Sciences
Abstract
ABSTRACT Deep‐ultraviolet (deep‐UV) nonlinear optical (NLO) crystals are crucial for generating deep‐UV lasers, and their performance is determined by the type, ratio, and arrangement of microscopic NLO functional units. Currently, there are no suitable materials capable of achieving deep‐UV phase‐matching (PM) laser output via direct second harmonic generation (SHG) at around 148.3 nm — a key requirement for the 2 2 9 Th nuclear clock. Here, we proposed a functional‐units‐ratio design principle to address this bottleneck. Applying this strategy to the Li‐B‐O‐F system, we designed two novel compositions, LiB 3 O 4 F 2 and Li 2 B 4 O 5 F 4 . Subsequent crystal structure prediction identified C 2‐LiB 3 O 4 F 2…
