Laser Etching
Over the years our memories fade. These days photographs are stored as files on our computers or locked away in cupboards and rarely seen. So why not let us at Your Perfect Memory, create a unique keepsake or gift to keep that memory alive for all to enjoy.
Wouldn't it be wonderful to capture that birthday, wedding, anniversary, graduation or any other wonderful moment in beautiful crystal, where it lives on forever, and can be seen and enjoyed over and over again.
Our amazing laser technology can accurately reproduce any photograph as a 2D image, with personalised message in beautiful solid optic crystal.
How do we do it? We take a digital picture or scan of a traditional photo and have these images etched into optically perfect laser crystal without damaging the surface. We only offer the finest quality crystal which is sometimes referred to as K-9.
A scientific class laser driven by a very sophisticated computer software program creates an actual 2-dimensional image within a flawless piece of optically clear solid crystal. A concentrated laser beam is programmed to penetrate the crystal and create a miniature dot within.
Following a precise sequence, tens of thousands of these imploded dots form an exquisite design. Since the laser is non-invasive, it leaves no marks or blemishes to mar the surface of the crystal. When viewed the intricate design is like a 2-dimensional sculpture. Beams of light are refracted in thousands of directions creating a dramatic presentation.
Scientific Explanation
Light is actually an electro-magnetic wave and thus has an electric field. A laser beam, also known as coherent light creates an electric field greater than 10 million volts per centimeter. The focus of the laser beam creates "free" or unattached electrons. The "free" electrons, accelerated by the electric field created by the laser beam causes the high energy electrons to collide with atoms and ions in the focus area. As the process continues it causes a chain reaction and produces about 1 million trillion free electrons per cubic centimeter in about 1 trillionth of a second.
Multi-photon absorption is used to create this crystal art. The process involves focusing a "light fantastic laser beam" to a spot (about one-tenth of the diameter of a human hair) within a block of optically perfect crystal. The laser then emits a short pulse beam (a few billionths per second) and produces a tiny micro crack. The systems then perfectly align and position tens of thousands of additional micro cracks to create 2D or 3D images. Although, the laser generates power densities of 10 billion watts per square centimeter, the surface of the crystal is NOT damaged due to the highly transparent nature of optically perfect crystal. The resulting images appear to float within the crystal.
