Patent ID: 7413147

Claim:
A method to stabilize a distance between a first apparatus and a second apparatus, comprising: attaching a laser thrust system to said first apparatus and said second apparatus; activating said laser thrust system, wherein said laser thrust system provides a repelling force that repels said first apparatus and said second apparatus away from one another; and attaching a tether system to said first apparatus and said second apparatus, wherein said tether system provides an attracting force that attracts said first apparatus and said second apparatus towards one another, wherein said repelling force and said attracting force are substantially equal to stabilize said distance of said first apparatus and said second apparatus, and wherein attaching said laser thrust system to said first apparatus and said second apparatus comprises: attaching a laser to said first apparatus; attaching a first mirror to said first apparatus; attaching a second mirror to said second apparatus; and positioning said first mirror and said second mirror, wherein a laser beam generated by said laser transmits through a back of said first mirror to form an intracavity laser beam, and wherein said intracavity laser beam reflects off of a front of said first mirror and a front of said second mirror a plurality of times.
