Active Control of Random Lasing Using the Optical Trapping Technique

Not Accessible

Your library or personal account may give you access


A method to control the random laser action of particle-dispersed media using the optical trapping technique is proposed. By focusing a trapping beam into a small region of the scattering medium, some of the scattering particles are trapped in that region, causing the distribution of scatterers inhomogeneous. According to the experimental results, the emission intensity of the spectral peak varies, depending on whether the trapping beam is on or off. Other spectral features caused by the particle trapping are also examined.
