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 a bandwidth-limited pulse could be transformed into a chirped pulse (with a filter only acting on the phase) or into a more complex pulse (with the filter acting on both phase and amplitude). One can distinguish FT pulse shapers by their optical design: i.e., collinear shapers and transverse shapers, and by their programmability, i.e., static (or manually adjustable) shapers and programmable shapers. Femtosecond pulse shaping In optics, femtosecond pulse shaping refers to manipulations with temporal profile of an ultrashort laser pulse. Pulse shaping can be used to shorten/elongate the duration of optical pulse, or to generate complex pulses. Generation of
