A microsurgical laser device for guiding a laser beam to a desired target. The device includes a laser head that is vertically oriented and which is supported by a base that contains the required electronics for the system. This laser head can be tilted in all directions so as to position the device for use. The laser head is coupled to an articulated delivery system that allows for the delivery system, including a colposcope or an operating microscope, to be raised, lowered, tilted, rotated, and focused onto the target. The articulated connection from the laser head to the colposcope or operating microscope makes use of a minimum number of mirrors to redirect the laser beam at 90 degree angles along a direction perpendicular to the axis of the incident path. Each mirror is mounted on precision mounts that obviate the need for adjustments. In one embodiment of the device the articulated system makes use of three mirrors to redirect the beam and one lens to provide a fixed laser spot size at the target. In another embodiment of the device, four mirrors are used and two lenses are employed in order to provide a variable laser spot size at the target.
