Dhansak them the tradition of cooking meat with lentils and/or vegetables. However, tomatoes, chilies, pumpkin and potatoes are native to the Americas and were unknown in India until some time after the Portuguese (who in turn got them through trade with Spain) brought them to India in the 16th century CE. The dhansak is flavoured with a spice mixture called "dhansak masala", which is similar to "garam masala" except that the spices chosen are more aromatic and sweet rather than pungent. Cinnamon, cardamom, cloves, nutmeg, dried ginger, coriander seed and cumin seed, as well as a pinch of asafetida, are among
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
