abstract and introduction

Method & materials

The following materials were used in of the construction of this experiment: green laser, lens with focal

length f=125, Translation Stage, PM121D - Digital Power & Energy Console, Si Sensor, 400 nm -1100

nm, 500 nW - 500 mW , and razor blade

At first we measured the beam waist of the green laser, The laser was directed to the direction of the beam

detector, and we installed the razor blade in the x-axis between the laser and the detector at the translation

stage, and then the razor blade was moved in the x-axis in small increments to prevent the laser light until

the whole light was blocked. Setup can be seen in figure1.

fig1, Experimental setup

Next, the green laser beam waist was measured at the focal point. We fixed the lens with a focal length of

125 mm between the laser and the translation stage. The razor blade is placed on the translation stage at

the focal length of this lens. Then we used the same approach in the first part. See figuer1.

Data was recorded in Originpro 9.1.
