Abstract: PROBLEM TO BE SOLVED: To overcome any difficulty in attainment of a tunable diode laser absorption spectroscopy (TDLAS).SOLUTION: A multiplexer 16 optically-connected with outputs of two or more diode lasers 12 having selected laser oscillating frequencies is optically-connected with an optical fiber on pitch side. A multiplexed laser beam is transmitted to a pitch optical component 20 associated with a process chamber 22 through the pitch side optical fiber. The pitch optical component 20 is oriented so as to radiate a multiplexed laser output through inside the process chamber. A catch optical component 24 receives the radiated multiplexed laser output. The catch optical component 24 is optically-connected with an optical fiber transmitting the multiplexed laser output to a demultiplexer 28. The demultiplexer 28 demultiplexes a laser beam to optically-connect the selected laser oscillating frequency of the laser beam with a detector 25. This detector has sensitivity to one of the selected laser oscillating frequencies.

Abstract: A method of sensing a process utilizing a sensing apparatus consisting of more than one diode laser having select lasing frequencies, a multiplexer optically coupled to the outputs of the diode lasers with the multiplexer being further optically coupled to a pitch side optical fiber. Multiplexed laser light is transmitted through the pitch side optical fiber to a pitch optic operatively associated with a process chamber which may be a combustion chamber or the boiler of a coal or gas fired power plant. The pitch optic is oriented to project multiplexed laser output through the process chamber. Also operatively oriented with the process chamber is a catch optic in optical communication with the pitch optic to receive the multiplexed laser output projected through the process chamber. The catch optic is optically coupled to an optical fiber which transmits the multiplexed laser output to a demultiplexer. The demultiplexer demultiplexes the laser light and optically couples the select lasing frequencies of light to a detector with the detector being sensitive to one of the select lasing frequencies.
