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
Ultrashort pulse the amplitude of ultrashort pulses. To accurately control the pulse, a full characterization of the pulse spectral phase is a must in order to get certain pulse spectral phase (such as transform-limited). Then, a spatial light modulator can be used in the 4f plane to control the pulse. Multiphoton intrapulse interference phase scan (MIIPS) is a technique based on this concept. Through the phase scan of the spatial light modulator, MIIPS can not only characterize but also manipulate the ultrashort pulse to get the needed pulse shape at target spot (such as transform-limited pulse for optimized peak power, and other
