    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: PROBLEM TO BE SOLVED: To provide method and system for monitoring and control of combustion that overcome any difficulty in attainment of wavelength-variable diode laser absorption spectroscopy (TDLAS). SOLUTION: In this method, multiplexer 16 optically-connected with output of two or more diode lasers 12 having selected laser oscillating frequencies is optically-connected with optical fiber on pitch side. Multiplexed laser beam is transmitted to pitch optical component 20 associated with process chamber 22 through the pitch side optical fiber. The pitch optical component 20 is oriented so as to radiate multiplexed laser output through inside the process chamber. A catch optical component 24 receives the above radiated multiplexed laser output. The catch optical component 24 is optically-connected with the optical fiber transmitting the multiplexed laser output to demultiplexer 28. The demultiplexer 28 demultiplexes laser beam to optically-connect the selected laser oscillating frequency of the beam with a detector 25. This detector has sensitivity to one of the selected laser oscillating frequencies. COPYRIGHT: (C)2010,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To solve the problem for achieving the tunable diode laser absorption spectroscopy (TDLAS). SOLUTION: A multiplexer (16) optically coupled to the outputs of more than one diode lasers (12) having selected lasing frequencies, is further optically coupled to a pitch side optical fiber. Multiplexed laser light is transmitted through the pitch side optical fiber to pitch optics (20) operatively associated with a process chamber (22). The pitch optics (20) are oriented to project multiplexed laser output through the process chamber. Also catch optics (24) receive the projected multiplexed laser output. The catch optics (24) are optically coupled to the optical fiber which transmits the multiplexed laser output to a demultiplexer (28). The demultiplexer (28) demultiplexes the laser light and optically couples to detectors (25) the selected lasing frequencies of light. Each of detectors (25) is sensitive to one of the selected lasing frequencies. COPYRIGHT: (C)2009,JPO&INPIT
