A method and device for reducing the timing jitter in a passive Q-switched Nd:YAG solid state laser by spatially selective bleaching a thin sheet of a saturable absorber of Cr+4:YAG from a direction orthogonal to the direction of laser emission where the Cr+4:YAG transmission increases 18% when the bleaching probe beam is a single laser diode bar. The auxiliary handle attachment generally includes a mounting structure having a first channel member including a first channel and a second channel member including a second channel aligned with the first channel, an auxiliary shaft extending upwardly from the mounting structure, and an auxiliary handle extending from the shaft. Its Brix and acid, and thus Brixacid ratio, are measured or estimated. 5 \u03bcm CMOS IC, Double Poly Double Metal, n-well technology and allows the integration of the on-chip signal conditioning circuitry. A current is injected into the electronic module thereby compensating for the presence of the electronic module during the testing.
