Definitions
- a beam with a Gaussian irradiance profile When a beam with a Gaussian irradiance profile is propagated through the active GRIN lens of the invention, its irradiance profile is transformed into a uniform profile in a z-plane of the material (forming length) determined by the properties of the medium.
- the condition for obtaining a uniform irradiance profile for a shaper of length d can be written as: or, what is the same, when the half-width of the laser beam w tends to infinity at the output of the former.
- q and Q represent the position and slope of the complex ray that propagates along the active material, respectively, while q * is the conjugate complex of q.
- the substrate is immersed in a colloidal solution prepared by sol-gel technology and subsequently removed from it at a constant speed.
- the variation in the speed with which the substrate is removed makes it possible to obtain coatings of different thicknesses. Typical speeds are between 1 and 40 cm / min, typically between 5 and 25 cm / min.
