Experimental Analysis of Laser Beam Spatial Profile at Sallahadin University, Slides of Laser Physics & Quantum Optics

Salahaddin University (Kurdistan Region) (SU)Laser Physics & Quantum Optics

Laser PhysicsOpticsElectromagnetism

Data from an experiment conducted at the laser laboratory of the physics department at sallahadin university. The experiment involved measuring the spatial profile of a he-ne laser beam, with dimensions and intensity recorded at various propagation distances. The document also includes calculations and discussions on the beam waist and quality of the laser.

What you will learn

How is the intensity of a Gaussian laser beam affected by propagation distance?
What challenges were encountered during the measurement of the laser beam's spatial profile in this experiment?
What is the significance of the beam waist in a Gaussian laser beam?
