RAPIDLY TUNABLE LASER SOURCE ASSEMBLY WITH LONG STROKE GRATING MOVER

RAPIDLY TUNABLE LASER SOURCE ASSEMBLY WITH LONG STROKE GRATING MOVER

A laser assembly (10) that generates a beam (12) includes (i) a gain medium (22) that generates the beam (12) when electrical power is directed to the gain medium (22); (ii) a grating (32) positioned in a path of the beam (12); (iii) a grating arm (34) that retains the grating (32); and (iv) a mover...

Zusammenfassung:A laser assembly (10) that generates a beam (12) includes (i) a gain medium (22) that generates the beam (12) when electrical power is directed to the gain medium (22); (ii) a grating (32) positioned in a path of the beam (12); (iii) a grating arm (34) that retains the grating (32); and (iv) a mover assembly (36) that moves the grating arm (34) about a pivot axis (38). The mover assembly (36) includes a coarse mover (344) that makes large scale movements to the grating arm (34), and a fine mover (352) that makes fine movements to the grating arm (34). With this design, the mover assembly (36) can quickly and accurately move the grating (32) over a relatively large range.
