KTA Crystals for Optical Parametric Oscillation

In this article, we discuss the distinctive features of KTA crystals, their application in optical parametric oscillation, and a comparative analysis with Potassium Titanyl Phosphate (KTP) crystals.

Optical Basics: The Nature of Light and Optical Elements

This article aims to provide a comprehensive understanding of essential Optical Basics, ranging from the nature of light (including wavelength, the electromagnetic spectrum, phase and amplitude, the wave-particle duality of light, to reflection, refraction, birefringence, and interference) to the operation principle of optical elements.

Nd:YVO4

Nd:YVO4 is an important material in laser technology. Nd: YVO4 refers to neodymium (Nd) doped into yttrium orthovanadate (YVO4) crystal, forming a composite material with excellent optical properties. This material is widely used in laser technology, particularly in solid-state lasers.

Understanding Optical Specifications-Geometric Specifications

A guide that helps understand the glossaries of optical specifications including thickness diameter tolerance, angle tolerance, center error, radius of curvature, clear aperture, parallelism, etc.

Understanding Optical Specifications: Surface Specifications

This article offers a simple but thorough explanation of surface specifications, which is an essential subset of optical specifications and which include Surface Quality, Surface Flatness, Surface Roughness, Power, Irregularity, and Fracture/Chip. This knowledge will help you navigate the complexities of optics terms and enhance your grasp of optics concepts.
