We propose two methods for generating SC pulses from narrower band pulses using 7-fused silica thin plate array. The first method is to increase the number of thin fused silica plates and optimize their position arrangement. The second method is to employ induced-phase modulation by the second-harmonic pulses. We obtain SC pulses ranging from 450 to 900 nm.
