The light is polarized, but the state will be changed depending on bending and stressing of the SM fiber. In general, using a collimating lens with a short focal length will result in a small collimated beam diameter and a large beam divergence, while a lens with a large focal length will result in a large collimated beam diameter and a small divergence. Try to set up a high power laser diode (visible betw. The new page will go live shortly. Post appropriate warning signs or labels near laser setups or rooms. Thorlabs Laser Diodes, Unbiased LASER DIODE SELECTION GUIDE, Compare all Manufacturers and Product Data Sheets on One Site, 370nm to 2350nm. Can you recommend me a correct fit; please? For example, either the A390-B or the A390TM-B could be used as these lenses each have an NA of 0.53, which is more than twice the approximate NA of our laser diode (0.26). Diodes are arranged by wavelength and then power. The laser's specified output power is the sum over the full spectral bandwidth. Assuming that the width of the lens is negligible compared to the radius of curvature, the thin lens approximation can be used to determine the appropriate focal length for the asphere. For this reason, current sources are typically used. One special thing is we want to put these diodes in an external cavity configuration to control the emission wavelength. For this application, the ideal lens is a molded glass aspheric lens with focal length near 5.6 mm and our -B antireflection coating, which covers 780 nm. I see your laser driver LD3000R but it is written that it supports A, D and E pin config.
