M.Tech in Laser Engineering
Lasers have become a integral part of our lives. They are used in CD/DVD drives, laser printers, surgical and clinical equipments, precision welding and cutting equipments, in various flow measurement equipments, in remote sensing and defense equipments, in holography, communication equipments, in alignment and leveling instruments etc. The field of application is expected to grow in future as the scientific community moves ahead towards the realization of quantum computers, quantum communication, 3-D data storage devices, terahertz networks etc. Since the application of lasers spans across various disciplines of science and engineering and the science behind laser itself is a conglomeration of ideas from diverse branches of science and engineering, this field of lasers and its applications is best addressed in the form of an interdisciplinary area of study and research.
The Center for Laser Technology(CELT) at IIT Kanpur is geared towards research in various specialized applications of lasers like laser spectroscopy, laser-plasma studies, ultrafast phenomena, bio-medical optics optics, photonic devices, semiconductor lasers, interferometric tomography, optical networks,particle image velocimetry, laser schlieren, etc.
The Laser Technology Program is an interdisciplinary MTech program aimed at producing laser scientists to meet the growing need for expertise in the field of lasers and its applications. It was started in July 1988 with the aim and objective of training young Engineering and Science graduates for providing skilled manpower in the specialised field of lasers and photonics. The curriculum has been designed to provide the necessary theoretical and experimental background in lasers, quantum optics, and various laser applications such as optical communications/networks & switching, holography, material processing, materials and biomedical spectroscopy, flow/temperature & stress analysis, optical signal processing & computing and optoelectronic integration. Compulsory laboratory courses constitute an integral part of the curriculum. Each student is required to take up a two semester long research project in any one of the laboratories associated with the laser technology programme.The students make use of the facilities of the Centre for Laser Technology, which consolidates the research and developmental activities in this field. In addition to the usual classroom teaching, emphasis is on hands-on experience on lasers. The compulsory courses on Laser Technology Laboratory Techniques facilitate the process. Depending on the problem chosen, students carry out their M.Tech. projects in the laboratories of the centre for Laser Technology (CELT) or in those of the departments stated above.
Course Structure of the M.Tech Programme
Each postgraduate student admitted in the programme is required to register in every semester till he/she completes the requirements of his/her programme. These requirements are counted in terms of units which roughly reflect the number of contact hours. Normal load in a semester is 16 units.
The minimum residence requirement for students registered in M.Tech. Programme is four semesters. They are required to complete a minimum of 64 units of which at least 24 units should be through course work and at least 28 units should be through research work.
In order to graduate at the Master's level, students must obtain a minimum CPI of 6.50.
