Newly Installed Facility

To meet the upcoming challenges, one has to evolve and upgrade continuously. Therefore, we are also

preparing our centre equipped with state-of-the-art facilities to keep it in mind. In that process, we
recently set up a high-power LPY700 series Nd-YAG laser from Litron UK. These pulsed lasers are
suitable for our research that requires high energy. The laser can operate in pulsed mode giving the
maximum energy of 1.2 joules. The laser can emit a principle beam of wavelength 1064 nm and the second

harmonic at 532 nm.

The specifications of the laser are mentioned below:

Model No: LPY674-10

Repetition Rate: 10 Hz
