We demonstrate the use of transient IR absorption measurements for picosecond thermometry of protein in an aqueous environment. For small temperature changes, measured transient absorption changes are shown to be in excellent agreement with the "stat

We define five unique cellular responses to thermal stress using a reporter construct generated using the stress-inducible promoter from the gene encoding a murine 70 kDa heat shock protein (Hsp70A.1) to express luciferase (luc). Thermal stress was d

The detailed shape of picosecond optical pulses from a free-electron laser (FEL) oscillator has been studied for various cavity detunings. For large values of the cavity detuning the optical pulse develops an exponential leading edge, with a time con

Experiments are presented on a mixture of tungsten hexacarbonyl (W(CO) 6 ) and (acetylacetonato)dicarbonylrhodium(I) (Rh(CO) 2 acac) in liquid dibutylphthalate (DBP) in which the spectrum of the asymmetric CO stretching modes (∼2000 cm −1 ) is ta

Mid-infrared transient absorption (“pump−probe”) measurements on the amide I band of myoglobin in D2O and in a glass-forming D2O/glycer(ol-d3) solvent mixture reveal very rapid vibrational energy r...

Pulse stacking, or synchronous pumping, is a novel approach that offers important advantages in cavity ring-down spectroscopy. Using an ultrashort pulse, high repetition rate laser source we have shown that it is possible to resonantly stack pulses i

We have measured the temporal pulse shape of a mid-infrared free electron laser using a 60 fs Ti:sapphire pulse as an optical gate. By employing a differential technique to simultaneously measure the instantaneous infrared intensity and its time deri

We have implemented a control system for the free electron laser (FEL) and its linear accelerator which allows us to produce independently controlled FEL beams multiplexed on a macropulse time scale. In this paper, we discuss the generation of multip

We present a method for the remote generation of a transient near-field probe using conventional IR microscopy optics. Photo-induced reflectivity generated by picosecond pulses of visible light incident on the surface of a semiconductor substrate is

Requests for beam time at the Stanford Picosecond Free Electron Laser Center far exceed the amount available. We describe our efforts to increase the available beam time by interleaving pulse trains of different wavelengths and delivering these to di
