Chennai, Feb 4 : Researchers at the Indian Institute of Technology-Madras (IIT-M) have demonstrated the possibility of generating bio-compatible lasers from carrots, exploiting a process first discovered by Sir C.V. Raman who won the Nobel Prize for Physics in 1930.
This finding by the IIT-M team, a first-of-its-kind development even globally, promises significant advancements in scientific and industrial research on optical spectroscopy and sensing. ''Apart from being bio-friendly, the system they envisage is robust and reliable with good and linear response to temperature'', a release from IIT-M on Monday said.
Being completely natural and fully bio-compatible, this system could be used with other bio-entities for their sensing based on the proposed laser. ''Being very robust and highly reliable, this ‘kitchen laser’ has very good and linear response for temperature which could be used for temperature sensing too'', it said.
Lasers were ubiquitous sources of light with extraordinary properties such as high degree of directionality and sharpness. They were indispensable in a dazzling range of products and technologies including communication, lithography, medicine, military operations, scientific research, engineering, displays and data storage.
In this case, a particular class of lasers called ‘random lasers’ have been demonstrated in carrots where a Raman process plays a central role along with the cellulose network, the release said.
Prof C Vijayan of IIT-M Physics department said “there is now a move towards development of green, sustainable materials for various applications, including in photonics. The need for green photonic technologies in obvious in the current times where sustainability, bio-compatibility and degradability are of paramount importance.”(UNI)
