We illustrate that applying the optical Kerr effect technique to dimethyl sulfoxide (DMSO) can determine the width of laser pulses in a wide spectrum range that is transparent. Different from many other simple molecular liquids, such CS2, and toluene, DMSO responds to both 130 fs 800nm laser pulses and 248 fs 400 nm laser pulses with electronic motions only. Therefore, the observed signal as a function of time reflects the temporal distribution of the intensity. We verify our illustration by both the autocorrelation technique and spectra analysis.

Excellent optical thermometry based on upconversion emission in SrMoO_4:Er^3+ phosphor

Optical Materials Express (2017)

Zhen Huang Zhongquan Nie Mubiao Xie Yuxiao Wang Dongyu Li

In this paper, SrMoO4:Er3+ phosphor excited by 976 nm diode laser shows remarkably intense green and relatively weak red upconversion emissions. Subsequently, within the temperature range from 310.8 K to 629.4 K, we tested a temperature-dependent fluorescence intensity ratio originating from the thermally coupled 2H11/2 and 4S3/2 states. It is revealed that SrMoO4:Er3+ phosphor exhibits a high sensitivity of 0.0326 K−1 at 554.0 K, indicating that the phosphor can be regarded as a promising building block for optical temperature sensor.

Off-resonant reverse saturable absorption in copper phthalocyanine at steady-state

Acta Optica Sinica (1993)

Yuxiao Wang

Reverse saturable absorption (RSA) was obtained in the solution of copper phthalocyanine (CuPc) by using a 532 nm Q-switched laser. Two seady-state expressions describing reverse saturable absorption for the thin sample and the thick sample, respectively, have been obtained by using the rate equation theory. The theoretical analysis is consistent with the experimental result.
