Fibre Sensors & Optical Spectroscopy Section (FSOSS) is involved in the design, development and applications of high beam quality, high repetition rate (5-20 kHz) visible and UV coherent radiation sources. The radiation sources are based on in-house developed Copper Vapour Lasers (CVLs), their nonlinear second harmonic and sum frequency conversion and CVL pumped wavelength tunable dye lasers. These visible/UV high repetition rate, nanosecond, sources are being utilized for the development of optical fibre gratings and for isotope selective high resolution spectroscopic studies particularly on the element Lithium. The instrumentation related to lasers, fibre sensors and isotope separation are being developed in-house.
FSOSS has indigenously established fibre Bragg grating (FBG) inscription facility. FBGs fabricated by this facility are being utilized in various applications such as temperature sensing, strain sensing and refractive index sensing. Field deployable Raman scattering based optical fibre distributed temperature sensors (OFDTS) are also being developed. These single point and distributed temperature sensors are suitable for temperature monitoring in high EMI, nuclear radiation and chemically hazardous environments. As per users’ demand, customised fibre sensors are being provided to Indian Industries and National Institutes under the aegis of ‘RRCAT Incubation Centre’.
The current R&D activities of FSOSS are:
