1. A system for locating a target surface of ocular tissue in an irido-corneal angle of an eye for photodisruption by a laser, the system comprising:
a laser source configured to output a laser beam;
a dual aiming beam apparatus configured to transmit a first aiming beam of light and a second aiming beam of light;
an optics subsystem optically aligned with the laser source and the dual aiming beam apparatus to receive the laser beam, the first aiming beam of light, and the second aiming beam of light, the optics subsystem comprising a focusing objective configured to:
direct the laser beam, the first aiming beam of light, and the second aiming beam of light along an angled beam path through a cornea and an anterior chamber of the eye, to be incident with the target surface of ocular tissue in the irido-corneal angle of the eye, and
align the first aiming beam of light and the second aiming beam of light relative to each other and relative to the laser beam such that the first aiming beam of light and the second aiming beam of light intersect at a point corresponding to a focus of the laser beam; and
an imaging apparatus optically aligned with the optics subsystem to capture an image of the irido-corneal angle including a first spot corresponding to the first aiming beam of light and a second spot corresponding to a second aiming beam of light.
