PURPOSE: A DC discharge sealed type carbonic acid gas laser resonator for 200W is provided to increase the length of resonance by using two gas sealing tubes. CONSTITUTION: A DC discharge sealed type carbonic acid gas laser resonator for 200W includes a couple of gas sealing tubes(P1,P2), the first reflective mirror(M1), the second reflective mirror(M2), a reflective mirror fixing plate(MM1), a light speed connection portion(B2), the first and the sixth reflective mirrors(M1,M6), and the third and the fourth reflective mirrors(M3,M4). The first and the second reflective mirrors(M1,M2) are fixed to the gas sealing tubes by using the reflective mirror fixing plate. The resonant length of laser is increased by using the light speed connection portion. A resonator is controlled by using the first and the sixth reflective mirrors. The third and the fourth reflective mirrors are installed within the light speed connection portion. The reflective mirror fixing plate is installed at the gas sealing tubes.
