![]() ![]() S = δ Τ 4 var that best describes the combined impact of temperature profile and beam shape. Specifically, it is the spherical aberration factor If it is a good approximation to describe the beam-induced temperature rise by means of a fourth-order even polynomial, the degradation in beam quality originates entirely from the quartic term δT 4 ρ 4. It is the purpose of this paper to formulate simple procedures for assessing the impact of such aberrations in a cw regime and to provide a prescription on how to proceed in the context of designing or evaluating Faraday rotators for CO 2 laser systems. This creates radial temperature gradients and, in conjunction with a nonuniform beam pattern, may lead to severe wavefront aberrations. For this reason, the semiconductor-based isolators, which are of promise for applications at 10.6 μm, must be cooled. ![]() Note: Author names will be searched in the keywords field, also, but that may find papers where the person is mentioned, rather than papers they authored.įaraday rotation isolators for CO 2 laser radars must be capable of handling substantial average power loads without degrading the beam quality or experiencing thermal runaway.Use a comma to separate multiple people: J Smith, RL Jones, Macarthur.Use these formats for best results: Smith or J Smith.For best results, use the separate Authors field to search for author names.Use quotation marks " " around specific phrases where you want the entire phrase only.Question mark (?) - Example: "gr?y" retrieves documents containing "grey" or "gray".Asterisk ( * ) - Example: "elect*" retrieves documents containing "electron," "electronic," and "electricity".Improve efficiency in your search by using wildcards.Example: (photons AND downconversion) - pump.Example: (diode OR solid-state) AND laser.Note the Boolean sign must be in upper-case. Separate search groups with parentheses and Booleans.Keep it simple - don't use too many different parameters. ![]()
