FBG based distributed feedback laser for sensor applications

FBG based distributed feedback laser for sensor applications

Distributed feedback fiber laser (DFB-FL) is a kind of laser consisting of a single phase shifted fiber grating directly writing in the rare earth doped fiber, depending on the narrow bandwidth, low noise, and stable single-mode operation. In this project, CGCRI...
Up-scaling of refractory crucible for glass melting

Up-scaling of refractory crucible for glass melting

RSW glass melting in indigenously developed 10L coarse body refractory crucible with fine body layer by tilt casting method using 10L scale Raising Hearth furnace, has been successful. This is currently being scaled up to a 60L scale using in-house fabricated 60L...
Tannery waste water treatment using membrane bioreactor

Tannery waste water treatment using membrane bioreactor

Tannery effluent was collected from a leather processing unit located at Bantala leather complex, Kolkata and characterized in detail. The effluent showed typical value of COD 6500 mg/L, BOD5 1000 mg/L and Cr+6 content of 70 mg/L. Batch mode bioreactor studies were...
Development of pulsed Yb-fiber laser for marking

Development of pulsed Yb-fiber laser for marking

A ‘ready-to-use’ Pulsed Yb-Fiber laser module has been developed. M/s Spinks Impex, Gurugram, completed thorough performance evaluation of 20W pulsed fiber laser module by synchronizing their existing marking system with the indigenously developed electronic...
