<title>Picosecond nonlinear excitation and nonlinear spectroscopy of polyatomic molecules at 10 um</title>

Abstract

all, the lO-1u m pulses with high energy contrast were generated. Secondly, a resonant probe four wave mixing method can be applied because of presence of the powerful picosecond solid-state laser pulse O-8194-1300-3/94/$6.OO SPIE Vol. 2041 / 193 Downloaded From: http://proceedings.spiedigitallibrary.org/ on 06/25/2016 Terms of Use: http://spiedigitallibrary.org/ss/TermsOfUse.aspx SPIE Vol. 2041 / 203 Downloaded From: http://proceedings.spiedigitallibrary.org/ on 06/25/2016 Terms of Use: http://spiedigitallibrary.org/ss/TermsOfUse.aspx

Two-color emission of BaWO4 crystals pumped by 472 nm 0.11 ps laser pulses for frequency conversion into the longwave IR domain

“…The laser system master oscillator [4] was based on difference frequency generation (DFG) of a picosecond near-infrared (NIR) laser pulse and its Raman-shifted (Stokes) pulse. It should be noted that the idea for the effective use of nonlinear optical conversion with fine-tuning to the gain band of a high-pressure CO 2 laser (used as a power amplifier) was proposed previously in [7,8] as well as some of its applications [9].…”
