A two-course meal of sambar mixed with rice and eaten with some sort of vegetable side dish, followed by yoghurt mixed with rice, is a prime southern Indian staple. "Vada" sambar and "idli"
Femtosecond pulse shaping picosecond separation implies transmission of optical information at very high speeds. In ultrafast laser science pulse shapers are often used as a compliment to pulse compressors in order to fine-tune high-order dispersion compensation and achieve transform-limited few-cycle optical pulses. A pulse shaper may be visualized as a modulator. The input pulse is multiplied with a modulating function to get a desired output pulse. The modulating function in pulse shapers may be in time domain or a frequency domain (obtained by Fourier Transform of time profile of pulse). However, application of direct pulse shaping technique on a femtosecond time scale faces
