SFU News Online – Beaming in on lasers – May 13,

A flash tube—which Maiman acquired from a photographic supply catalogue—is coiled around the bar. At the focus, microscopic particles can be “trapped” held stable, in solution and the forces acting on them can be probed.

Comments Commenting is closed Comment Guidelines. The laser pioneer, who died inwas nominated three times for a Nobel Csa. Geographer Jeremy Venditti is trying to understand the role that turbulence plays in riverbed deposits and erosion.

She plans to continue the workshops this fall along with graduate and undergraduate student volunteers and other physics department staff. More than students attended the dozen two-hour Burnaby campus workshops, using lasers in hands-on caz to learn about reflection, refraction and the nature of electromagnetic radiation. Quantum mechanics is becoming important, says McGuirk, because “as electronics become smaller and smaller, classical physics will no longer be able to describe their behaviour.


And this year the Radiation Safety Office is planning to offer 2001 new course to train non-university laser users who are interested in becoming laser-safety officers for their organizations.

SFU established a laser safety program 10 years ago to ensure the safe use of lasers lasoors campus. SFU a laser safety pioneer Rapid advances in laser lawors are expanding its use in a variety of fields, yet its potential hazards—particularly serious eye damage—are not always recognized.

Scattering intense laser light off the atoms exerts enough force to cool the gases to a few millionths of a degree above absolute zero. He was always looking to create some kind of spark.

As the light rays bounce between the mirrors at each end, they stimulate further light emission from other excited atoms. Her research group is using these particles as handles to stretch single molecules.

Ted, along with many other scientists, joined the race. Physicist Jeff McGuirk uses lasers in his atomic physics lab to cool and trap the gases of atoms.


The optical tweezers focus laser light through a microscope objective lens. The kids particularly enjoyed “creating optical mazes from mirrors and glass and using Jell-O to model how light travels in a 20100 optic cable,” says Moll. His last project was a vertical start airplane—nothing even close to a laser.

Forde aims to relate the sequence of proteins to their mechanical function, which may provide insight into the mechanisms of connective-tissue diseases. But a laser generates “coherent” light, which means its waves move in one direction and at the same wavelength, producing a powerful monochromatic or single-coloured beam.
