LASER OSCILLATING DEVICE

摘要

Support part (20a) supporting an OPM holder (15a) so that the OPM holder (15a) is perpendicular to the axis of the laser beam is disposed under the OPM holder (15a). A rotary shaft (19) is passed through the support part (20a) and a rotary shaft support part (20b), and thereby the OPM holder (15a) and a DT base (17) is combined. These constitute a rotation support unit (200). The rotation support unit (200) has a degree of freedom of rotation in the direction indicated by the arrow (202). A support bar (21) is attached under an RM holder (15b). A rotary body (22) and a rotary body support part (23) supporting the rotary body (22) is provided on the DT base (17) side to support the support bar (21). These constitute a slider structure (220) slidable along the optical axis. The slider structure (220) has a degree of freedom in the direction indicated by the arrow (222).
