Abstract

The coherence spike of femtosecond laser pulses in the reflection-type pump-probe measurements has been systematically studied in the semiconductor (100) InP. By varying the setup of the pump-probe measuring system, i.e. the polarizations of pump and probe pulses, the incident angles of pump and probe beams, and the interval of delay time between pump and probe pulses, the dramatic changes in the strength of coherence spike could be clear observed. Furthermore, the proposed methods to remove the coherence spike from the transient reflectivity curves have been demonstrated in the time-domain measurements.

Figures (4)

Fig. 1.
Fig. 1.

The transient reflectivity change of InP. The thin line represents the second-order autocorrelation trace. The dashed line indicates that the transient reflectivity change under the separation of pump and probe spots on the surface of samples. The inset shows the coherence spike on an enlarged scale. The dashed line in the inset is the first-order interferometric autocorrelation trace. All of the polarization configurations are pump ⊥ (the polarization of pump pulses is perpendicular to the incident plan) and probe ‖ (the polarization of probe pulses is parallel to the incident plane). All of the measurements were performed at θpump =1°, θprobe =7°, and the interval of delay time Δt=0.33 fs.

(a) Schematics of a reflection-type pump-probe measurement and the generation of a transient grating in materials. The thick lines represent the pump beam. The thin lines represent the probe beam. The thick arrows represent the diffracted light at various orders (m=0,+1,-1,…). θG =θpump +θprobe (b) The spectra measured at θ=8° (from the surface normal of samples). (c) The spectrum obtained by subtracting the spectrum with thick line from the spectrum with thin line in (b).

The coherence spike in ΔR/R under four polarization configurations (a) pump ⊥ (the polarization of pump pulses was perpendicular to the incident plan) and probe ‖ (the polarization of probe pulses is parallel to the incident plane), (b) pump ‖ and probe ‖, (c) pump ‖ and probe ⊥, (d) pump ⊥ and probe ⊥. The inset of (a) is that the measurements were performed with and without the polarizer in front of the detector. All of the measurements were performed at θpump =1°, θprobe =7°, and the interval of delay time Δt=0.33 fs.
