For laser beam diagnostics, a "virtual cathode" system was realized at the photogun bench located in the Veksler and Baldin Laboratory of High Energy Physics (LHEP) of the Joint Institute for Nuclear Research (JINR). The system allows one to image laser beam profile at the cathode. For imaging, the AVINE software suite developed in DESY Zeuthen is used. Equipment for emittance measurement using the slit method was installed. The original emittance calculation software EmCa was created and tested with laser beam.
