Abstract
We have experimentally studied thermal effects in highly pumped Ti:sapphire crystals in the 140-340 K temperature range. We demonstrate that a critica l temperature exists, which depends on pumping and probing conditions, belo w which detrimental thermal effects completely disappear. In particular, we show that in a typical high-intensity Ti:sapphire amplifier, thermal lensi ng and wave-front distortions can be suppressed keeping the crystal tempera ture lower than similar to 230 K.
