Abstract: A method for photoacoustically sensing oxygen in a gaseous sample is disclosed, together with an apparatus for practicing the present method. Efficient and cost-effective oxygen sensing is provided by the use of a light source in the form of a light-emitting diode, which can be selected to correspond with the absorption spectra exhibited by oxygen in a gaseous sample. Filtering can be employed in order to control and narrow the wavelength of light emitted by the light source. An apparatus is disclosed which facilitates practice of the present method, including an arrangement by which ambient noise and vibration can be canceled.

Abstract: In a first embodiment, the invention makes use of a Neodymium doped YAG (Nd:YAG) gain medium placed in an optical resonant cavity formed by two mirrors. Power extraction is maximized for a specific laser cavity. In particular the concave curvature on the rod ends contributes a negative lensing component to modify the strength of the thermal lens. In a second embodiment the present invention uses an amplifier rod medium with curved ends to act as lensing elements to collect emission from the laser gain medium and/or oscillator described in the first embodiment of the invention. The combination of thermal lens and curved rod ends produces a lensing effect which allows light to be directly coupled from a laser. In addition, variation of the input pump power allows for control of the thermal lens formed within the amplifier rod.
