Sambar (dish) powder. In Andhra Pradesh, it is called as "Pappu chaaru". Apart from dal and tamarind, vegetables used in preparing is few. Vegetables are onions, dosakaaya, bitter gourd and tomatoes. Sambar without lentils (but with vegetables, or dried or fresh fish) is called kuzhambu in Tamil Nadu. Sambar is usually served with steamed rice as one of the main courses of both formal and everyday south Indian cuisine. 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"
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
