A gas laser interferometer has been devised by utilizing coherent property of beams from opposing ends of a gas laser. With this interferometer under various conditions, several interference experiments are made with interference fringes that appear by superposition of two beams from opposing ends of Gihe laser. Some characteristics of gas laser can be obtained from the study of these interference fringes. For example, the existence of spatial coherence between the said two beams; possibility of observation about the conditions of spatial coherence and wavefront seen in mode patterns by superposing and shearing the beams; formation of ring-type interference fringes and its interpretation; and the phase reversal occurring here and there in the mode pattern and its demonstration
