Ultrafast Photonics Laboratory (UPL) primarily works in two domain : Building of ultrafast fiber and solid state lasers and THz Spectroscopy and Imaging. The laboratory hosts state-of-the-art equipment in realizing these while offering M. Tech. and Ph. D. programs as per DIAT Pune's criteria. UPL is committed to work with the vision and mission of DRDO, with nation first policy.
