1. A multimodal imaging system comprising:

  • a laser apparatus for generating a laser beam capable of irradiating a biological sample;

    an optical coupler operatively connected to the laser for collecting photons reflected from the biological sample, wherein the optical coupler is selected from the group consisting of a 2×

    2 single mode optical coupler and a free-space based beam splitter having a pinhole;

    a dual-axis scanner operatively connected to the laser for scanning the laser beam across the biological sample;

    an optical device for delivering the laser beam to the biological sample; and

    an ultrasonic transducer for measuring laser induced ultrasonic waves.
