Femtosecond anti-Stokes conical emission in BK-7 glass and O and E-wave calcite
Abstract
The angle of anti-Stokes conical emission (CE) is experimentally measured in the frequency shift span of 2000 c m − 1 to 9000 c m − 1 . The experiment was performed using a 800 nm 50 fs laser pump in samples of BK-7 glass and calcite in both the O and E-wave configurations. The experimental results of angular emission are then compared to three competing models: the Alfano–Shapiro four wave mixing (FWM) model from 1970, the Luther FWM model from 1994, and the Faccio X-wave model from 2004. Results indicate that in all samples and configurations tested, the original FWM has the best agreement with experimental results in the anti-Stokes span.
