Two-tint pump-probe measurements using a femtosecond laser oscillator and sharp-edged optical filters

Abstract: We describe a simple approach for rejecting unwanted scattered light in two types of time-resolved pump-probe measurements, time-domain thermoreflectance (TDTR) and time-resolved incoherent anti-Stokes Raman scattering (TRIARS). Sharp edged optical filters are used to create spectrally distinct pump and probe beams from the broad spectral output of a femtosecond Ti:sapphire laser oscillator. For TDTR, the diffusely scattered pump light is then blocked by a third optical filter. For TRIARS, depolarized scatteri… Show more

“…This setup uses a Spectra Physics tsunami femtosecond laser working at a repetition rate of 80 MHz and 790 nm wavelength 16 , the beam of which is split into two parts, the pump (used to heat the sample surface) and the probe (to measure the reflectivity of the sample surface), which are focused on the same spot at the sample's surface. The pump beam passes through a sharp long wave-pass filter set a 790 nm and the probe passes through a short wave-pass filter set at the same wavelength.…”

“…The experimental setup used for the TDTR experiments is a coaxial two-tints pump/probe experiment 16 and has already been described in detail elsewhere 11 .

“…In this study, we use a two-tint implementation of this method as described in Ref. 31. Briefly, a Ti:sapphire laser oscillator generates a series of femtosecond pulses at a repetition frequency of 76 MHz and wavelength of 785 nm.…”

“…To compare to experiment, we use previously reported measurements on Si at cryogenic temperatures as well as new TDTR measurements of thermal conductivity versus pump size at room temperature using a standard two-tint TDTR setup. 34 The sample consists of a high-purity Si (resistivity >20000 X-cm) substrate coated with 70 nm Al transducer using electron-beam evaporation. The pump 1/e 2 diameter is varied from 60 lm to 3.7 lm, while the probe 1/e 2 diameter is kept constant at 9.5 lm for pump diameters greater than 15 lm and 2.7 lm otherwise.…”
