Intrinsic pulsewidth dependence of third-order nonlinear optical susceptibility

We demonstrate that second-order nonlinear optical susceptibility /spl chi//sup (2)/ and third-order nonlinear optical susceptibility /spl chi//sup (3)/ are related, in part, and that /spl chi//sup (3)/ has intrinsic pulsewidth dependence even with a single nonlinear constituent.

Full characterization of third harmonic generation in CsLiB/sub 6/O/sub 10/ (CLBO) crystals

We investigated a full characterization of third harmonic generation of a Nd:YAG laser in CsLiB/sub 6/O/sub 10/, crystals. Theoretical analyses and experimental results are presented for the effects of different types of third-order nonlinear interactions.

Second-order cascading effects in LiB/sub 3/O/sub 5/ crystals

The second-order cascading effects in LBO crystals, which have high optical damage threshold and wide transparency range from 155 nm to 3.2 /spl mu/m, was investigated in the vicinity of non-critical phase-matching temperature by temperature tuning. Non-critical phase-matching temperature was measured and the dependence of phase mismatch on temperature was investigated. The nonlinear transmittance and nonlinear phase shift, as a function of temperature, were also measured.
