A high power laser available at midinfrared(MIR) region is much expected for machinery, welding and medical uses,combining with optical fibers transparent at the corresponding wavelengths. In order to couple intense beam into a tiny fiber effectively, extremely careful alignment of optics such as lens and mirror is indispensable in a conventional scheme. Thus, one of the authors has proposed a new method in which the optical fiber is directly inserted into the coupling-hole of the resonator mirrors in intra-cavity laser, and called it the fiber-coupled or Dynamite laser.1)However, since the coupling hole on the mirror disturbs the field distribution by itself, it is very important to take account of the field disturbance for optimum coupling to provide the maximum output power.
