Diffracted light intensity versus time for a suspension of Pt particles with diameters of irradiated with a laser pulse. On a time scale of several milliseconds, the signal decays to the baseline.
Diffracted light intensity versus time for a suspension of Pt particles irradiated with laser pulses. On a time scale of several milliseconds, the signal decays to the baseline.
Diffracted light intensity vs time for a suspension of diameter Pt particles in water irradiated by the picosecond laser. The fringe spacing in the grating was . The inversion of the signal relative to that in the previous two figures comes as a result of directly feeding the photomultiplier signal to the oscilloscope as opposed to using an inverting preamplifier.
Photomultiplier output voltage vs time for an aqueous carbon suspension. The laser energy was per pulse. The absorption coefficient of the suspension at the laser wavelength was adjusted to be . Inset: The same signal, but displayed on a shorter time scale.
Transient grating signal from diameter Pt suspensions (a) without and (b) in a solution saturated with . The laser energy used to obtain both traces was . The fringe spacing was . Trace (a) decays to the baseline on a ms time scale; trace (b) does not.
Diffracted light intensity (photomultiplier output voltage) vs time for a transient grating experiment with an aqueous solution of uranyl oxalate and oxalic acid, where the ratio is (a) 0, (b) 0.75, and (c) 1.55. The laser wavelength and energy are , per pulse, respectively.
Ratio of the bubble radius to its intial radius vs dimensionless time, as given in Ref. 26 for a gas bubble with heat capacity ratio , an initial pressure ratio relative to the pressure at infinity of 100, and (a) , (b) , and (c) .
