argon-ion laser News
Quantum Dots Are Finding Their Place in the World
Apr 12, 2010 — There has been a panoply of research into the next big thing in quantum dots – those semiconducting artificial atoms that are ubiquitous in fluorescence imaging, biological and chemical sensing, and display applications. Quantum dots of more (or less) exotic materials and with more (or less) interesting shapes are demonstrated on almost a weekly basis. It is the heyday for the field. But getting less attention are the practical issues of handling quantum dots in such a way that their...
Lasers Serve the Muse
Sep 1, 2006 — Paula Dawson, a pioneer and reknowned exponent of using holographic images as a fine art form, has been exhibiting laser-based works in galleries and museums worldwide since the late 1970s. Her triptych, Eidola Suite, an installation on view in the...
Up-Conversion Fiber Laser Produces Visible Output
Aug 1, 2004 — Lumics GmbH of Berlin has developed a visible-wavelength source based on an up-conversion fluorozirconate (ZBLAN) fiber laser that has emission lines comparable to those from an argon-ion laser. It works by exploiting the absorption of rare-earth...
Optical Stimuli Control Magnetism in Novel Materials
Oct 1, 2003 — In 1886, Heinrich Hertz observed that utraviolet light, when directed at a conduction plate, caused an increase in electrical charge. Einstein later articulated this as the photoelectric effect and explained how light waves or photons exist in...
Solid-State Lasers Are Gunning for Argon-Ion's Place
Sep 1, 2003 — Frequency-doubled diode lasers that produce blue light at or near 488 nm have emerged over the past couple of years, potentially affecting the multibillion-dollar instrumentation market based on the air-cooled argon-ion laser that has evolved over...
