Lasing due to pair emission of exchange coupled Cr³⁺ ions in the LaCr_0.5Ga_0.5O₃ perovskite system is reported by M. S. Ramachandra Rao, K. Sethupathi, and co‐workers in article number 2000519. A laser threshold value of 73 W cm⁻² is obtained at room temperature and a better threshold of 35 W cm⁻² is observed near 100 K. The pair emission is confirmed with the help of lifetime and electron spin resonance spectroscopy analysis.
