Free space output version of the MATCHBOX laser Integrated Optics SMA fiber port output is particularly convenient in setups where the laser has to be switched from one source to another without changing anything else in the setup This is often the case in metrology or in fluorescence or Raman spectroscopy systems when radiation wavelengths are changed by switching to another laser source This form of laser output can be used only with multimode fibers as the SMA connector features some tiny loose space between the ferule and the interior of the connector as well as repeatability of the fiber attachment features poor repeatability Figure 2 4 SMA port output version of the MATCHBOX laser MatchBox series User Manual Permanent fiber pigtailed output has few modifications though it looks essentially the same The difference is in the fiber type Multi mode single mode or single mode polarization maintaining fiber could be arranged within this output type It is readily used in microscopy and diagnostic setups where few laser sources are placed in a distance from the analytical device e g a microscope and radiation of several wavelengths is delivered to the microscope via optical fibers Lasers with non detachable fibers usually feature higher fiber coupling efficiency as compared to SMA port output thus more optical power is useful Figure 2 5 Fiber pigtailed output version of the MATCHBOX laser Integ
