Abstract.

Broadband amplification of laser pulses at 400 nm is demonstrated with a maximum gain of 3550 using non-collinear optical parametric amplification. Without depleting the pump, the spectral gain was found to be almost flat along the available 17-nm-wide spectrum of the signal pulse. It is also shown that the group velocity difference between the signal and pump pulses eventually results in an even broader amplified spectrum. The extension of this technique to other UV wavelengths can also be accomplished, so that femtosecond laser pulses between 300–400 nm can be directly amplified.
