    Introductio to Laser Resonator & Beam Quality
    A simple optical resonator consists of two mirrors. Its most significant character is the open sides which always produce diffraction losses. The functions of a laser resonator are (a) to achieve optical feedback and to generate laser beam; and (b) to restrict laser beam and to form a coherent beam.
