Optic large deflection cantilever beam (OLDCB) method



  1. Computer Engineering, Ankara Yıldırım Beyazıt University, Ankara, Turkey


In this experimental study, "Optic Large Deflection Cantilever Beam, OLDCB" method has been developed for calculating laser beams bending. OLDCB method is mathematically correlating and methodizing the information obtained from experimental results. OLDCB is defined regardless of wavelength and phase shift. In the experiment, lenses with a special geometric structure, which are independent of the wavelength and phase shift made of glass, were used. Semiconductor single mode green laser source was used as the source in the study. The optical output power of this laser source is 5-50 mW and the spectral bandwidth is 100KHz. There is no special condition for bending the magnetic field, electric field or laser beam in the experimental environment and it was carried out in the laboratory under atmospheric conditions. Only lenses that have been developed have been used for laser beam bending. We think that this experimental study result should add new terms as a contribution to the science of optics. These new optical terms are; bending limit value of laser beam optical power, laser beam critical minimum optical power, laser beam critical maximum optical power, laser beam critical bending resistance, optic resistance, critical laser beam diameter, maximum laser beam diameter, minimum laser beam diameter, laser beam bending critical conditions, optic surface area resistance and laser beam bending angle, laser beam minimum bending angle, laser beam bending range, laser beam boundary angles and laser beam bending in special conditions can be added. These terms have been defined as dependent on optical variables and have been added to optical science..
