Beam selector for a photocoagulator

In a laser system including a first laser and a second laser rigidly mounted to a housing, and wherein said system includes optical means for alternately directing the beam from one of the two lasers to the output of the systems, said optical means including an apparatus for selectively intercepting and redirecting the beam from the first laser, said apparatus comprising:

• frame means pivotally mounted with respect to said housing and movable between a first and a second position;
• means for moving said frame means between said first and second positions;
• and
• a pair of spaced apart mirrors mounted to said frame means, said mirrors being independently adjustable to facilitate the aiming of the beam from the first laser, said mirros being mounted at a location such that when said frame means is in said first position, said mirrors are positioned out of the path of the beam of both said first and second lasers permitting the beam from the second laser to travel along a path leading to the output of the system and when said frame means is in said second position, said mirrors intercept and redirect the beam from said first laser along a path leading to the output of the system.

In a laser system including a primary laser and a dye laser where the beam from the primary laser is used either alone or to pump the dye laser, and wherein said primary and dye lasers are rigidly mounted to a housing, and wherein said system includes optical means for directing the beam from the primary laser along one of two paths, with one path terminating in the cavity of said dye laser to provide a pump source, said optical means including an apparatus for selectively intercepting and redirecting the beam from the primary laser along one of said two paths, said apparatus comprising:

• frame means pivotally mounted with respect to said housing and movable between a first and a second position;
• means for moving said frame means between said first and second positions;
• and
• reflector means, mounted to said frame means at a location such that when said frame means is in said first position, said reflector means is positioned to permit the beam from the primary laser to travel along the first path and when said frame means is in said second position, said reflector means intercepts and redirects the beam from said primary laser along said second path.

An apparatus for selectively intercepting and redirecting the beam from a laser comprising:

• a support means mounted to a housing;
• frame means pivotally mounted to said support means and movable between a first and a second position;
• means for moving said frame means between said first and second positions one of said positions defining a downward resting position;
• reflector means, mounted to said frame means at a location such that when said frame means is in said first position, said reflector means is positioned out of the path of the beam from said laser and when said frame means is in said second position, said reflector means intercepts and redirects the beam from said laser along a different path;
• and
• means for adjusting the coarse position of said frame means, said means being defined by an adjustment screw, threaded through said frame means and located in a manner to abut said housing when said frame means is located in the downward resting position.
