Sambar is also served as a side dish for dosa. Sambar (dish) Sambar, also spelled sambhar or sambaar, and pronounced saambaar, is a lentil-based vegetable stew or chowder, originating from the Indian subcontinent, cooked with a tamarind broth. It is popular in South Indian and Sri Lankan cuisines. According to food historian K. T. Achaya, the earliest extant mention of sambar in literature can be dated to the 17th century. Sambar is made either
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
