    "abstract": "Diode lasers enable one to continuously cover the 730 to 1100 nm range as\nwell as the 370 to 550 nm range by frequency doubling, but a large part of the\nelectro-magnetic spectrum spanning from green to red remains accessible only\nthrough expensive and unpractical optically pumped dye lasers. Here we devise a\nmethod to multiply the frequency of optical waves by a factor 3/2 with a\nconversion that is phase-coherent and highly efficient. Together with harmonic\ngeneration, it will enable one to cover the visible spectrum with semiconductor\nlasers, opening new avenues in important fields such as laser spectroscopy and\noptical metrology.",
