Abstract: Automatic background signal removal for input data, such as for spectrometry data, is provided. Input data includes input pixel points, such as those read by a CCD spectrometer of chromatography device, and intensity values corresponding to the data points. A distribution of changes in the intensity values between the data points is determined, and a noise level is judged by setting a threshold for the distribution. A noise region is identified as a predetermined number of consecutive input points for which the changes in the intensity values are within the noise level. Adjacent noise regions may be connected and the background signal is thus determined and subtracted. A spike noise region may also be identified and filtered, such that a peak obtained from fewer than a second predetermined number of the pixel points is determined as a spike, not a true peak. Non-spike large amplitude noises are optionally filtered.

Abstract: A hybrid Q-switch device for a laser device having a laser medium being pumped with energy includes a solid-state saturable absorber element for controlling loss modulation of the laser medium; an active Q-switch element having open and closed states for controlling loss modulation of the laser medium and positioned in series with the laser medium and the absorber element; and, a device for adjusting timing of the open and closed states of the active Q-switch element. The combined loss modulation control from active Q-switch and absorber elements enable generation of a short width, high peak power pulse at a lasing wavelength. Particularly, the loss modulation effects of active and passive Q-switch means are timed to minimize cavity loss at which time a high peak power pulse of small pulse width is generated.
