    摘要: A laser apparatus which is capable of terminating a irradiating operation using a laser beam without fail by opening switches even if a component of an irradiation switch unit have trouble during the irradiating operation in a continuous irradiation mode. A first switch (11) and a second switch (12) are connected electrically in series by signal lines (18) and are disposed in a side-by-side arrangement. An operating member (13) is a pedal for a foot switch or the like and is capable of substantially simultaneously closing and opening the first switch (11) and the second switch (12) in substantially the same degree. The irradiation switch unit may further be provided with a cover (16) for covering the operating member (13). In a continuous irradiation mode or the like in which a laser beam can be emitted for a time equal to or nearly equal to a time interval in which the irradiation switch unit are operated, a laser beam can be emitted only when both the first switch (11) and the second switch (12) are turned on.

    摘要: There is provided a laser operation apparatus capable of emitting suitable laser light having a uniformed light intensity distribution. A fiber vibrating device is fit to a portion of an optical fiber that guides laser light oscillated (for treatment) by a treatment laser light source to a slit lamp. The fiber vibrating device itself is vibrated by rotating a weight provided eccentric about a rotational shaft by a motor, thereby vibrating the optical fiber in a direction substantially orthogonal to an axial line direction thereof. When the optical fiber is vibrated by the fiber vibrating device, the laser light guided through the optical fiber is mixed to uniform the light intensity distribution of the laser light. The laser light having the uniformed light intensity distribution is emitted to an eye to be operated by the slit lamp.
