Claim 0:
1. An ophthalmic laser system comprising:
a beam sampler, comprising a plate made of a transparent material with a front surface and a back surface, wherein the beam sampler is configured to receive a laser beam at the front surface, to form a first sampled beam by reflecting a first fraction of the laser beam by the front surface, to form a second sampled beam by reflecting a second fraction of the laser beam by the back surface, the second sampled beam exiting the front surface, and to transmit a portion of the laser beam out of the back surface;
a first light detector and a second light detector respectively disposed to receive and detect the first sampled beam and the second sampled beam, the first and second light detectors being independent of each other;
an objective lens, disposed to receive the laser beam transmitted through the beam sampler and to focus the laser beam to a focal point in a target, wherein the objective lens is further configured to receive a laser light reflected or scattered from the target to form a return beam toward the back surface of the beam sampler,
wherein the beam sampler is further configured to form a third sampled beam by reflecting a fraction of the return beam by the back surface; and
a third light detector disposed to receive the third sampled beam.
