| Popis: | International audience; Tunable coherent sources emitting in the Long Wave Infra Red (LWIR), between 7 and 14 µm can be used in defense application such as standoff detection of hazardous gas and chemical warfare agents. In a previous ANR/DGA project called MUSTARD, we demonstrated, in the laboratory, a single longitudinal mode optical parametric oscillator (OPO) emitting in the 8-11 µm domain. This OPO used a quasi-phase-matched (QPM) GaAs crystal, pumped by a Tm:YAP microlaser [1] [2]. Now we present the development, as part of the DGA SPICE project, of a compact (~600 cm² footprint) and robust industrial prototype (Figure 1) based on the same architecture including an original setup for real time measurement of the emitted wavelength. |
