Ultrafast optical Kerr effect in CS2 at 10.6 μm

Abstract

This letter reports experiments that used a mode-locked TEA CO2 laser to modulate a cw He–Ne laser. This technique uses the optical Kerr effect in CS2. The optical Kerr coefficient, n2, at 10.6 μm is estimated from our data to be approximately 10−20 m2/V2.

Laser-fusion program. Semiannual report, January--June 1973

“…By using the optical Kerr effect in CS 2 , coupled with a visible probe beam and a streak camera, an ultrafast but nonlinear detection system can be created. The theory of operation of this detection scheme has been described in previous reports 58 ' 59 ; the work reported here is the direct continuation of the development described previously.…”

Laser-beam profiles in liquid : direct evidence for self-focusing of a laser beam in

“…Self-focusing of laser radiation in various nonlinear media, gases, liquids and solids has been studied [1][2][3][4][5][6][7][8]. The effect has been observed in liquid CS 2 by many investigators, using various techniques at various laser wavelengths but with a high-power beam.…”

Generation of coherent, broadband X-ray and mid-IR pulses in a noble-gas-filled hollow waveguide

“…In the above, A is the attenuation of the probe beam, L is the length of the waveguide, ݊ ଶ is the nonlinear index of refraction in ܿ݉ ଶ /ܹ and I is the laser intensity in ܹ/ܿ݉ ଶ [13]. On each shot we will measure the transmission of the probe as a function of pump intensity and extract ݊ ଶ as a fitting parameter.…”
