Abstract

We have used expansor and compressor grating-telescope pairs of novel design to stretch and subsequently recompress pulses from a frequency doubled YLF laser at 527 nm. The new design magnifies the time delay dispersion to a factor of 10 times larger than achievable with standard compressors of similar size. Figure 1 shows the experimental setup. The pulses of a frequency doubled Nd:YLF laser were spectrally broadened by self-phase modulation in a 98-m long monomode polarization preserving optical fiber to obtain a FWHM spectrum of 10.6 Ǻ. A fiber throughput of 20 % was obtained giving an output power of 200 mW. The Raman component at the output of the fiber had 30–45% of the energy of the fundamental spectrum. That spectral broadening can be routinely obtained at the output of the fiber, allowing for transform-limited pulses of 660 fs. However, optimization of the system after increasing the input power to 1.35 W allowed spectral broadening up to 16 Ǻ and compressed pulses as short as 480 fs measured with a spinning plate autocorrelator. This system in its first stage is similar to the scheme described by Johnson for pulse compressing the output of a Nd:YAG laser.1
