Hello Users and Zemax Staff,
The design I am working on is transient grating. I would like to ask if there is a possibility to use a 300fs laser pulse as light source. Because when using pulsed beam if the two paths differ with more than the pulse length then the beams might overlap in space but not in time and there will be no interference pattern. I want to use Zemax to simulate how the beam movement influences transient grating. Thanks!
Best,
Wanyu

Hi Wanyu,
It’s a great question. OpticStudio has no time-based analyses, so your best chance is to define multiple wavelengths and wavelength weights to represent the spectral bandwidth of the beam, and then to use whatever polychromatic wavefront analyses you can to see how the wavelengths interfere.
Please report back on how well this works out, it sounds very interesting.
