Profile: Lambda Photometrics Ltd. supplies lasers, optics, fibre optics, electronic instrumentation, surface metrology and machine vision products. We provide mode-locked picosecond fiber lasers that produce 1 to 10 ps pulse width signals at repetition rates of 5 to 11 GHz, and 38-42GHz. Its stability and ease of use are key features of these designs, which provide short warm-up and setup times as well as long term stability, low amplitude noise and low timing jitter. When used together with bit rate multipliers (BRM's) and pulse compressors, these sources allow advanced component and system development up to 320 Gb/s. We offer fibre optic temperature measurement sensors for laboratory, industrial, medical and transformer winding applications. The patented fibre optic temperature probe uses fluorescence to determine the temperature to an accuracy of 0.1 C.
