| Title | High-energy single-longitudinal mode nearly diffraction-limited optical parametric source with 3 MHz frequency stability for CO(2) DIAL. | | Author(s) | Raybaut M, Schmid T, Godard A, Mohamed AK, Lefebvre M, Marnas F, Flamant P, Bohman A, Geiser P, Kaspersen P | | Source | Opt Lett 2009 Jul 1; 34(13):2069-71. | | Abstract | We report on a 2.05 mum nanosecond master oscillator power amplifier optical parametric source for CO(2) differential-absorption lidar. The master oscillator consists of an entangled-cavity nanosecond optical parametric oscillator based on a type II periodically poled lithium niobate crystal that provides highly stable single-longitudinal-mode radiation. The signal emission is amplified by a multistage parametric amplifier to generate up to 11 mJ in a nearly diffraction-limited beam with an M(2) quality factor of approximately 1.5 while maintaining single-longitudinal-mode emission with a frequency stability better than 3 MHz rms. This approach can be readily applied to the detection of various greenhouse gases. | | Language | eng | | Pub Type(s) | Journal Article
