Embodiment Construction

[0060] FIG. 1 shows the XRD pattern of the laser material of the present invention according to Example 1. This laser material is made using a uniaxial hot pressing method (to be described later). Figures 3 and 4 show electron microscope pictures of this material.

[0061] It can be clearly seen from the XRD pattern and from the microscope pictures that the material is pure phase and includes a homogeneous and dense polycrystalline compact body with a grain size of 10-50 μm.

[0062] Figure 2 shows the XRD pattern of the laser material of the present invention according to Example II. This laser material is made using an extrusion step method (to be described later). Figures 5 and 6 show electron microscope pictures of this material.

[0063] It can be clearly seen from the XRD pattern and from the microscopic pictures that the material is phase-pure and includes a homogeneous and dense polycrystalline compact body with large grain sizes in the (approximate) sub-millimeter range. ...

Abstract

The invention relates to a ceramic non-cubic fluoride laser material and methods of its manufacture.

Description

Technical field [0001] The present invention relates to laser materials and their preparation methods. Background technique [0002] Solid-state light sources are currently entering many different lighting applications and replacing traditional incandescent lamps and gas discharge lamps. For applications with the highest optical requirements (such as projection, fiber optic applications), lasers are considered ideal light sources. Many applications are now provided by semiconductor diode lasers. However, when the application requires the use of special wavelengths that are not reachable by semiconductor diodes, usually diode-pumped solid-state lasers will be used to generate the desired laser wavelength. [0003] For many types of these diode-pumped solid-state lasers, such as LiYF 4 (YLF) non-cubic ternary fluoride materials are commonly used materials. Prominent examples are: based on Pr:LiYF 4 Blue diode-pumped solid-state laser, which generates the missing green wavelength fo...
