Claim 10:
11. A method implemented in an ophthalmic laser system, the method comprising:
by a beam sampler, the beam sampler being a plate made of a transparent material with a front surface and a back surface, receiving a laser beam at the front surface;
by the beam sampler, reflecting a first fraction of the laser beam by the front surface to form a first sampled beam;
by the beam sampler, reflecting a second fraction of the laser beam by the back surface to form a second sampled beam which exits the front surface;
by the beam sampler, transmitting a portion of the laser beam out of the back surface;
by a first light detector, receiving the first sampled beam;
by a second light detector which is independent of the first light detector, receiving the second sampled beam;
by an objective lens, receiving the laser beam transmitted through the beam sampler and to focusing the laser beam to a focal point in a target;
by the objective lens, receiving a laser light reflected or scattered from the target to form a return beam toward the back surface of the beam sampler;
by the beam sampler, reflecting a fraction of the return beam by the back surface to form a third sampled beam; and
by a third light detector, receiving and detecting the third sampled beam.
