Room-temperature lasing in nanocrystalline Cr2+:ZnSe random laser

We report the first room-temperature pulsed lasing around 2.4 μm from the single-crystalline Cr2+:ZnSe powder active medium with particle sizes varying from hundreds of nanometers to micrometers. Pump energy density at laser threshold of ~34 mJ/cm2 has been observed.
