Non‐linear optical chalcogenides with a wide band gap (Eg) and excellent NLO properties are key materials for highly desirable multiwaveband tunable optical parametric oscillators (OPOs). We exploit the “electronic structure engineer bucket effect” to develop a novel dual‐waveband SrZnGeS4 with an u...
