We propose novel technique for detecting gravitational waves using facilities at LIGO with certain easy changes in the process of detecting gravitational waves based upon a novel technique of adding up of the extremely small phase difference in two laser beams generated through passing of one wavelength of a gravitational wave. The change suggested in performing of the gravitational wave detection experiment that is carried out at present will be aimed at achieving adding up such phase difference that is produced through passing of each successive wavelength such that the cumulatively obtained phase difference through passing of sufficiently many wavelengths of gravitational wave automatically becomes detectable. The new suggested experiment in brief will proceed as given below. We begin with usual experiment using high energy well regulated pulsed laser source. When one pulse of laser beam will be emitted to move towards beam splitter we remove the source and replace it by a perfectly reflecting mirror kept orthogonally to the direction of laser beam incident on the beam splitter, and further this mirror can be moved in backward/forward direction as per requirement, by keeping it orthogonal to the direction of incident laser beam. Suppose there is squeezing along arm A and stretching along arm B of the interferometer producing the (very small) phase difference in the interfering light waves reaching back to beam splitter and let this phase difference is undetectably small so that almost all light is directed back to this new perfectly reflecting mirror, the one that replaced the source. Now, keep this mirror at such distance that the light that will reflect back from this newly kept mirror that replaced the source to act as source and to proceed again to fall upon the beam splitter and again will start running through two arms of interferometer for second round there will be again squeezing along arm A and stretching along arm B of the interferometer. Because of such arrangement the same amount of phase difference will result again and this will add up in the phase difference created in the first round. After sufficiently many bounces on newly introduced perfectly reflecting mirror replacing the laser source this phase difference will build up to a value so that now all light will no more be directed towards mirror that replaced the source but some light will go towards detector to offer a conclusive proof for the existence of gravitational waves!
