    Abstract: The present invention relates to a method for determining at least one gas condition at a location in a combustion chamber of a power plant or a combined heat and power plant by means of a laser pulse. The method comprises emitting (S1) the laser pulse into the chamber, determining (S2) a first point of time at which the laser pulse is emitted into the chamber, detecting (S3) laser light backscattered by gas molecules at the location in the chamber, determining (S4) a second point of time at which the laser light backscattered by the gas molecules is detected, determining (S5) the location based on the first point of time, the second point of time, and a pulse length of the laser pulse, and determining (S5) the at least one gas condition at the location based on at least one characteristic of the backscattered laser light detected at the second point of time. A gas measurement system and a combustion system are also presented herein.

    Abstract: An optical pulse source 30 comprising a DPSS pump laser 31, a photonic crystal fibre (PCF) 35 and acousto-optic modulator (AOM) gating means 33. The pump pulses are coupled through lenses 32 to the AOM 33, synchronised to the pump laser 31 and operable to gate the pump pulses to a reduced repetition rate Rr = Rf/N, where Rf is the pump laser fundamental frequency. The pulses from the AOM 33 are injected via optics 34 into the PCF 35. Propagation through the PCF 35 causes the pulses to broaden spectrally to produce supercontinuum pulses. An optical pulse source comprising the optical pulse source 30 and an acousto-optical tunable filter (AOTF) operable to convert supercontinuum pulses into wavelength variable output pulses is also provided. A method of scaling the energy of the optical supercontinuum pulses is also provided.

    Abstract: Biological information measuring apparatus capable of automatically identifying a subject under test, and executing continuous measurement under a common measurement condition having selected a properly identified site at a high S/N ratio for relatively long hours as necessary, and also improving utilization efficiency of the output light of a laser. In the biological information measuring apparatus using a confocal optical system provided with a laser serving as a light source thereof, the biological information measuring apparatus comprises a laser drive means (14) for effecting AC-driving so as to cause pulsed light to be outputted from the laser, and wherein the skin of a finger (FG) is discriminated from a nail (a) thereof on the basis of a detection signal of the confocal optical system, and a portion of the skin, in a range of the nail epithelium (b) of the finger (FG) to the first joint (c) thereof, is indicated as a measurement region.
