We demonstrate the generation. spectral broadening and post-compression of second harmonic pulses using a thin beta barium borate (BBO) crystal on a fused-silica substrate as the nonlinear interaction medium. By combining second harmonic generation in the BBO crystal with self-phase modulation in the fused-silica substrate. we efficiently generate millijoule-level broadband violet pul... https://allfixelectricales.shop/product-category/dryer-drum-slide/
