英文摘要	A light source assembly (10) for a precision apparatus (11) includes a broadband light generator (12), an amplifier (14), and an optical filter (16). The light generator (12) generates a generator beam (22) that is directed at the amplifier (14). The amplifier (14) provides an amplified beam (24) by amplifying the generator beam (22). The optical filter (16) filters both the generator beam (22) and the amplified beam (24) so that an output beam (20) has a specific spectral width and a specific center wavelength, and so that the power available from the amplifier is concentrated within the desired spectrum. With this design, the light source assembly (10) can provide an output beam (20) having a spectrum determined by the filter and power which is not strongly dependent on the spectrum. For example, the output can have a specific, relatively narrow spectral width and a specific center wavelength, with sufficient power for use in precision measurement systems (11). Additionally, the output beam (20) can have sufficient spectral width to eliminate unwanted interference effects.
