Detection of a stimulated emission process as an inverse thermal lens signal

A stimulated emission process is detected by applying the transient thermal lens (TL) technique developed recently. The observed inverse TL signal compared with the conventional TL signal indicates that a convex thermal lens is created in the solution by the stimulated-emission process. The sensitiv...

Description
Summary:A stimulated emission process is detected by applying the transient thermal lens (TL) technique developed recently. The observed inverse TL signal compared with the conventional TL signal indicates that a convex thermal lens is created in the solution by the stimulated-emission process. The sensitivity and the advantages of this method are discussed.
