Effect of emitted qi on the polarized plane of a laser beam

The aim of this experiment is to observe the effect of qi on the orientation of the polarized plane of a laser beam emitted from an inner cavity He-Ne laser.

A plane glass which is placed 20 cm away from the laser. The angle between the normal of the glass plane and the laser beam is set equal to the Brewster angle of the glass (approx. 57 degrees). At this angle only the component of the beam which is perpendicular to the ground (Ip) can be reflected by the glass. The reflected beam is accepted by a Si photocell. the photocurrent is recorded by an autobalancing recorder.

Another Si photocell is placed 10 cm away from the end of the laser tube to monitor the stability of the output intensity of the laser.

Let the angle between the polarized plane of the laser beam and the ground be Ø (theta). When the polarized plane rotates through an angle delta(theta) under the action of qi, the change of Ip is then
Delta Ip = 2 x I sin(theta) cos (theta) delta(theta)
'I' is the beam intensity. From delta Ip, delta(theta) can be deduced.
During the experiment, nobody is allowed to stay in the lab. The door of the lab is locked and the apparatus works automatically.
From Dec. 1986 to Jan. 1987, two sets of experiments were done. In the first set, Yan Xin emitted his qi 7 km away from the laser lab, and the second set, 2000 km away.
Three apparent results were obtained in 7 km qi emission experiment. In the duration of 55 minutes of qi emission, the originally stable Ip showed fluctuations for 10 times. The fluctuation stopped when Yan Xin ceased his qi emitting.
Two apparent results were obtained in 2000 km qi emission experiment. Big fluctuation appeared after 20 minutes of qi emission. The fluctuation was modified by a series of ripples which we have never seen in any laser experiment before. This new phenomenon cannot be explained by any reasons other than the effect of qi.
These experiments give the evidence that the orientation of the polarized plane of the laser beam emitted from an inner cavity He-Ne laser, and hence the state of the laser can be affected by qi emitted from a long distance.
It should be pointed out that these experiments are of the qigong scientific research with remote qi emission.
