Coherent-Excimer Laser inauguration and a Seminar on Pulsed Laser Deposition at Sahyadri

Mangaluru: Sahyadri College of Engineering and Management (SCEM) organized a seminar on Pulsed Laser Deposition (PLD) on the occasion of Inauguration of Coherent-Excimer Laser on July 20, 2016 at Sahyadri Campus. The Chief Guest Dr. Burkhard Fechner and the Guest of honor Dr. Lalit Kumar inaugurated the Excimer Laser. The seminar was organized by Center of Excellence in Nano-science & Technology (CENT) in association with Departments of Mechanical Engineering and Electronics & Communication Engineering of Sahyadri College of Engineering and Management.

During inaugural address, Dr. Burkhard Fechner spoke about the historical perspective of lasers and especially, the origin of Excimer lasers starting from the early effort in the development of Excimer Lasers at Lambda Physik Germany. He also talked about Pulsed Laser Deposition (PLD) other applications of Excimer Lasers.

Prof. Richard Pinto explained the genesis of PLD starting with the first publication of the growth of superconducting film using Excimer laser in 1987. Then he also talked about the early effort of how PLD lab established at TIFR in 1990 followed by growth of thin films of complex materials of superconductors, ferroleectrics and Magneto resistive manganites. He thanked Dr. Manjunathh Bhandary, Chairman for funding the Excimer laser and also Coherent (Dr. Burkhard Fechner and Dr. Lalit Kumar) for co-sponsoring the Excimer laser.

Prof. Umesh M. Bhushi, during his presidential address, stated that the research effort is required for the advancement of the institute. He thanked both Dr. Burkhard Fechner and Dr. Lalit Kumar for co-sponsoring the Excimer laser and for sparing their valuable time for gracing this occasion.


Dr. Fechner received PhD in 1987 from University of Hannover, Germany, in “Laser Atomic Spectroscopy in High Electric and Magnetic fields”. Dr. Lalit Kumar as a head of Laser Science Services (I) Pvt. Ltd represents over 30 of the leading laser manufacturers from all over the globe, covering a wide range of products which includes: scientific and industrial laser systems, spectroscopy and microscopy equipment and imaging systems. The total cost of the laser with special gases for operation is about Rs. 1 Crore. The Coherent-Excimer Laser Complex-Pro 201 is the only gas laser with high energy over 750mJ in the west coast of India excluding the institutions at Mumbai.

Pulsed Laser deposition is a powerful technique for the growth of thin films of multi-component complex materials. The importance of the technique is such that it is possible to realize stoichiometry of elements of the complex material in the thin films grown by PLD. Further, PLD is a powerful technique for research; especially, when a material cannot be stabilized in bulk either due to the problem of ionic radius or due to variable valance state; such materials can be synthesized in the form of thin films by PLD. PLD is also very useful for the formation of Nano-materials. Hence, the inauguration of Excimer laser will act as nucleus for CENT and the research effort on thin films and Nano-materials is to make rapid progress, especially with collaboration with neighboring institutions and industry partners.

Prof. S. S Balakrishna, Vice Principal, Prof. Umashankar, Dean Acdemic, Dr. Rajesh Rai, HOD of Mechanical Engineering, A.J.I.E.T Mangalore, faculty members of the institute and researchers various institutes including Mangalore University were present during the program. Dr. Navin N. Bappalige, Department of Physics, SCEM delivered the vote of thanks.
