摘要:
The possibility of generating extremely intense picosecond pulses at 5.3 &mgr;m by frequency doubling a strong CO2laser pulse in Te is demonstrated. It is shown that free carriers generated by two‐photon absorption at the leading edge of the second harmonic perturb the indices of refraction and greatly reduce the conversion efficiency for the remainder of the pump pulse.
