METHODE ET DISPOSITIF D'EMISSION LASER POUR L'ANALYSE SPECTROSCOPIQUE D'UN ECHANTILLON |
摘要 |
<p>According to one aspect, the invention relates to a laser emission device for the spectroscopic analysis of a sample, comprising: a primary laser source (401) emitting a pump beam (I5) and an excitation beam (I2), said two beams being pulsed and having a nanosecond or subnanosecond pulse time; a non-linear optical fibre (406) into which the excitation beam is injected in order to form a probe beam (I4) having a wide spectral band; a device (405) for controlling the time profile of either the pump beam or the excitation beam, allowing compensation of the time spreading of the probe beam generated by the non-linear optical fibre, in order to obtain pump and probe beams having similar pulse times; and means (409) for spatially overlaying of the pump and probe beams for the spectroscopic analysis of the sample.</p> |
