All of these laser sources can be optionally coupled into a variety of optical fibres (such as multi-mode, single mode, or polarisation maintaining single mode) via different connector types. We recommend FC\/APC connectors for most applications, since they prevent back reflections that can interfere with laser stability.<\/p>\n<p><strong>Fibre coupling for a laser head from the LDH-FA Series Why fibre coupling?<\/strong><br \/>\nCoupling the laser beam into a fibre is useful to transport the beam light in a safe manner. But besides the prosaic function of light transportation, fibre coupling has the added benefit of improving the beam quality. For example, the typically elliptical beam shape of a collimated laser diode gets circularised into a round beam at the output of the fibre. Furthermore, coupling the light beam into a single mode fibre or a polarisation maintaining single mode fibre even permits to filter out all side modes of the diode in order to obtain a not only circular but also near TEMoo, gaussian distribution of the beam profile. In fact, for confocal microscopy setups, the coupling of a laser diode head into a polarisation maintaining single mode fibre is nearly a must.<\/p>\n<p><strong>Fibre coupling for a VisIR laser moduleCoupling efficiency<\/strong><br \/>\nNote that fibre coupling does always lead to a loss in optical output power. The typical coupling efficiencies for elliptical laser diode beam shapes is 40 % for single mode and 80 % for multi-mode. The typical coupling efficiencies for fibre amplified laser beam shapes is 60% for single mode and 80 % for multi-mode in the visible\/NIR range. At 355 nm the coupling efficiency in a single mode is typically of 50 %. Below 350 nm no fibre coupling is offered at the moment.<\/p>\n<p>An optional collimator at the fibre output can also be provided upon request.<\/p>\n<p>1 Except for a few butterfly-diode-based laser heads where a FC\/APC receptacle is used as output (e.g., LDH-P-F-1030, CPDL-S-F-1060). Some lasers do come with a fixed output fibre by default such as the LDH-P-FA-530B.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Fibre Coupling Solution for any PicoQuant Laser Available for all collimated free beam laser sources from PicoQuant (except below 350 nm) Various [&hellip;]<\/p>\n","protected":false},"featured_media":49336,"template":"","meta":{"_acf_changed":false,"footnotes":""},"product_brand":[],"product_cat":[109],"product_tag":[],"class_list":{"0":"post-49266","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-short-pulse-ns-ps-fs-lasers","8":"first","9":"instock","10":"shipping-taxable","11":"product-type-simple"},"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.6 (Yoast SEO v27.7) -
