1975 he became Professor of physics at the University of Applied Sciences Berlin and later at the Universidade Federal do Rio de Janeiro. He performed research on atomic and laser physics in Germany, Brazil and the United States. His teaching activities were related mainly on medical physics, especially laser technology in medicine. He published numerous scientific papers and 8 books on basic physics, lasers and holography.

The machines used by Ponoko are far higher in power than those available to individual users which makes Ponoko services considerably faster when dealing with volume orders. This directional room sign for the Crete, Greece-based Galaxy Hotel captures the hotel’s essence of where traditional meets contemporary and where sophistication greets functionality. The clear acrylic is edge lit, which allows the light to diffuse over the surface and catch on the engraved sections, making the numbers appear bright. While So Little Time Co. technically designs jewelry, this husband and wife team like to refer to their brooches, necklaces and earrings as wearables.
Module 4: Making it Cut — Refining Your Designs
For example, leather treated with chromium cannot be laser cut due to the release of chromium (a carcinogen). Another example is PVC which can be cut with ease but releases hydrochloric acid and chlorine in the process which is extremely harmful. Artist Sandra Fettingis uses laser cut white acrylic to create geometric wall hangings.

In addition, he served as Vice Dean of the Faculty of Mathematics and Natural Sciences at the TUB. In 1998, he joined the Supervisory Board of Laser Medicine Technology GmbH Berlin and worked as CTO and CEO from 2003 to 2013. In 1982 he became chairman of the Quantum Optics association of the German Physical and Society and the Society of Applied Optics. Projects with industrial applications include the preparation and characterization of multilayer systems for mirrors and filters, fiber optics and silicon nanophotonics. His worldwide cooperation is documented in more than 500 journal publications, 10 patents and several books in German, English and Russian language. Without the gain medium, the circulating light would become weaker and weaker in each resonator round trip because it experiences some losses, e.g. upon reflection at mirrors.

Typically, the Alpha is pumped by an ultra-low-noise Primus pump laser, which provides more than 8 W average output power at 1040 nm wavelength and 450 fs pulse duration at 42 MHz repetition rate. In addition, the Alpha can be operated with other pump lasers around 1 µm wavelength and enough power. Alpes Lasers offers a wide range of lasers with wavelengths ranging from 4 to 14 μm and powers up to several watts. This includes FP, DFB, THz, frequency comb and external cavity lasers in the mid-IR. Additionally, Alpes offers uniquely fast and widely tuneable lasers with our ET and XT product line.
Start Making Your Own Laser Cutter Projects
Since bamboo is 100% renewable, it’s an ideal choice for the eco-friendly crowd. You can make anything from jewelry, tableware and electronics enclosures to conference badges, signage, book covers, point of sale displays—and these laser cut ideas are just the tip of the iceberg of potential uses. And since you can heat acrylic to give it a bend, you can give your laser cutter projects a boost by taking it beyond the constraints of two dimensions. A good brainstorming session is a great place to start along with this guide to making bookmarks that will help put your creativity and personal touch into these popular laser cutter projects. They want decorations that are tailored to their unique personalities and tastes.
If the intensity of the 976nm pump light is high enough, the number of electrons in the metastable state exceeds the number of electrons that remain in the ground state. This state represents both the stimulated emission and the population inversion principles. The transition of the electrons back to the ground state causes emission of light with a wavelength corresponding to the energy difference. Desktop laser cutters are perfect for rapid prototyping of new ideas and concepts, creating custom laser engraved panels, and for artistic purpose.
There are many ways to attract eyeballs from a distance, and here’s a selection of laser cutter projects that we found particularly eye-catching in both wood and acrylic. By combining 3D software and high tech laser cutting techniques, artist Anthony Roussel creates stunning layered rings and bracelets that are inspired by modern architecture and seaside coastlines. Feeling artistic after seeing the creativity in these laser cutter projects?
We all learn differently, so I’ve included multiple ways to learn, from videos through to worksheets, with resources at your fingertips to access any time. This course will be presented through an easy to use online platform called Teachery. A learn as you need it approach, so you can learn the basics and build up your advanced skills over time, as you need them.
With an array of laser types, we can work on various shapes and sizes, and hundreds of types of materials like silicon, glass, aluminum, and more. For over forty years, Laserod and its predecessor companies have provided laser micromachining products and services to many of the largest industrial corporations and most prestigious universities in the world. Two become four, four become eight and so on until the photons are amplified enough for them to all move past the mirrors and the optical material in perfect unison. Think of them as synchronized members of a marching band in the Rose Parade. Laser beams can stay sharply focused over vast distances, even to the moon and back. A laser takes advantage of the quantum properties of atoms that absorb and radiate particles of light called photons.
MPE is now widely used in several areas of biological research, most notably neuroscience. Etsy seller decoylab adds laser cut white acrylic atop bamboo bases to create one-of-a-kind clocks. These laser cut white (and black!) acrylic bunny rings are a part of Etsy shop NocturneDesignsCut’s “cute animals” series.
