The Femtosecond laboratory at CAMP has two ultrashort laser oscillators. Femtosource scientific XL is delivering pulses as short as 50 fs with maximum pulse energy of 200 nJ at 5.2 MHz repetition rate. KM Lab Kit is another femtosecond oscillator delivering pulses of 1-2 nJ energy with 80 MHz repetition rate. Both lasers are operating at 800 nm central wavelength.

One of the active R&D programmes undertaken by this laboratory is on“Fabrication and submicron tailoring of materials for photonics applications with ultrafast lasers” and is funded by Office of Principle Scientific Advisor, Government of India. This is an out come of the ambitious research collaboration with Prof. Deepak Mathur’s research group at TIFR which has been growing since 2003. The project work focuses on the fabrication of active and passive waveguides inside transparent glasses for the telecommunication window using femtosecond lasers.

Laser Induced Forward Transfer of thin films is another experiment being conducted here. This techniqueinvolves the transfer of metal from a donor thin film to acceptor substrate that is kept sufficiently close toit. Micro patterns of metals, which have numerous applications in the field of microelectronics can bedeposited by this technique. Another notable study is the white light generation experiments using a photonic crystal fibre. With these works the femto team at CAMP seeks to develop integrated photonic circuits and devices.
