“…Reducing the intensity of the pump below 2/3 of the full power raises the amplitude noise in the output, and makes the system more critical to operate on a single longitudinal mode. Such a degrading can be overcome by using a different geometry optimized for lower pump levels, with better focussing of the cavity mode on the nonlinear crystals, and choosing different crystals with higher nonlinear polarizability [10].…”

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

“…As a result the power of the transmitted beam was very small compared to the input one, and not equal, as in the theoretical approach of the previous section. This is due to the fact that we used, instead of an optimized cavity, an existing one as used in the experiment described in ref [6].…”

We have developed a new method based on two cavities containing χ (2) media to reshape optical pulses by an all-optical technique. The system is entirely passive i.e., all the energy is brought by the incoming pulse and uses two successive optical cavities with independent thresholds. The output pulse is close to a rectangular shape. We show that this technique could be extended to high bit rates and telecommunication wavelength using very small cavities containing current nonlinear materials.

“…As an example, periodically poled lithium niobate (PPLN) is often used as a nonlinear crystal to fix the issue of phase mismatching. [3][4][5][6][7][8][9] However, a key disadvantage of using PPLN is its operational temperature of 100 • C to 200 • C to avoid the chances of photorefractive damage of the crystal during operation. At room temperature operation, a 5% MgO doped PPLN crystal would be preferable.…”
