Which bandpass filter is necessary to clean the beam of a Coherent MIRA Ti:sapphire laser operated in CW to make it usable for Raman excitation?

27 October 2016 1 5K Report

In my first attempt I noticed a large background which I attributed to unwanted emission from the gain medium. So I guess I need a bandpass filter to clean up the excitation spectrum and I would like help to select this device

Mauro Falconieri

Dear Yuriy thanks for you suggestion. Actually I know Semrock filters but I am not sure the Max-line filters are suitable for the application in terms of their bandpass and out-of-band rejection.
