Raman mode random lasing in ZnS-β-carotene random gain media
Raman mode random lasing is demonstrated in ZnS-b-carotene random gain media at room temperature. A self assembled random medium is prepared with ZnS sub micron spheres synthesized by homogeneous precipitation method. b-Carotene extracted from pale green leaves is embedded in this random medium....

| description |
Raman mode random lasing is demonstrated in ZnS-b-carotene random gain media at room
temperature. A self assembled random medium is prepared with ZnS sub micron spheres synthesized
by homogeneous precipitation method. b-Carotene extracted from pale green leaves is embedded in
this random medium. The emission band of ZnS random medium (on excitation at 488 nm) overlaps
considerably with that of b-carotene, which functions as a gain medium. Here, random medium
works as a cavity, leading to Raman mode lasing at 517nm and 527nm triggered by stimulated
resonance Raman scattering |
