▲ [15a-PB01-3] Nanosecond pulse compression by SBS technique and investigations of its SHG characteristics
キーワード：SBS, nanosecond pulse
We investigate pulse compression characteristics of moderate energy (~ mJ), tunable ns pulses from a Ti:Sapphire laser (15 Hz, 15 ~ 30 ns, 10 ~ 30 mJ, 680 – 1000 nm) operating in the gain-switching mode. We will demonstrate and describe a variable length, compact/folded SBS amplifier cell and discuss its performance dependence on the effective interaction length of the amplifier. We will present and discuss experimental results describing the wavelength-dependent compression characteristics of tunable nanosecond pulses in different media (FC72, FC40 fluorinates) in terms of energy conversion efficiency, pulse compression factor, and brightness.
Experimental investigations of the SHG conversion efficiency and stability of the compressed pulses in a broad spectral region are in progress. The results of these experiments will also be presented and discussed at the conference.
