Transparent material processing with an ultrashort pulse laser

Methods for ultrashort pulse laser processing of optically transparent materials. A method for scribing transparent materials uses ultrashort laser pulses to create multiple scribe features with a single pass of the laser beam across the material, with at least one of the scribe features being formed below the surface of the material. This enables clean breaking of transparent materials at a higher speed than conventional techniques. Slightly modifying the ultrashort pulse laser processing conditions produces sub-surface marks. When properly arranged, these marks are clearly visible with side-illumination and not clearly visible without side-illumination. In addition, a method for welding transparent materials uses ultrashort laser pulses to create a bond through localized heating. The ultrashort pulse duration causes nonlinear absorption of the laser radiation, and the high repetition rate of the laser causes pulse-to-pulse accumulation of heat within the materials. The laser is focused near the interface of the materials, generating a high energy fluence at the region to be welded. This minimizes damage to the rest of the material and enables fine weld lines.

Glass plate fusion for macro-gradient refractive index materials

A glass block (10) comprises a plurality of intermediate glass plates (12i) stacked between a top plate (12t) and a bottom plate (12b). The top and bottom plate each have a selected composition, with a particular index of refraction and a softening temperature. The intermediate plates have compositions intermediate those of the top and bottom plates and are stacked so as to provide a gradient in composition from top to bottom. Heating the assembly at a fusion temperature fuses the plates together to form the glass block. After cooling down to room temperature, the glass block can be shaped to make lenses and other light directing devices. Such lenses have a gradient in the refractive index of at least about 0.085, and gradients approaching 0.5 are achievable. The thickness of the glass block along the optic axis is fairly unlimited, and thicknesses on the order of 10 mm and more are routinely achievable by the process of the invention.

The process for bonding a room temperature substrate employs a step in which a first substrate that is substantially transmissive to a laser wavelength is selected. Subsequently, a second substrate for mating at the interface with the first substrate is selected. A change in transmittance is created at the interface and the first and second substrates mate at the interface. Subsequently, the first substrate is irradiated with a laser having a transmission wavelength substantially focused at the interface, and a local high temperature at the interface is generated due to the energy supplied by the laser. The first and second substrates in immediate proximity to the interface are softened by diffusion across the interface to fuse the substrates.

Method for fusing glass substrates using laser beam and laser processing apparatus

Two glass substrates are fused using a simple method and a simple apparatus configuration without deformation of processed end surfaces. This method for fusing glass substrates is a method in which two glass substrates in close contact are irradiated with a laser beam and fused together, and includes a first step and a second step. In the first step, a first glass substrate and a second glass substrate are brought into close contact. in the second step, the first glass substrate and the second glass substrate are melted and fused together by scanning a laser beam having a wavelength of 2.7 µm or more and 6.0 µm or less along a portion where the first and second glass substrates are in close contact.
