Self Referencing Heterodyne Transient Grating Spectroscopy with Short Wavelength
Heterodyning by a phase stable reference electric field is a well known technique to amplify weak nonlinear signals. For short wavelength, the generation of a reference field in front of the sample is challenging because of a lack of suitable beamsplitters. Here, we use a permanent grating which mat...
