Lessons learned from a recent laser accident In September 2009, a graduate student working at SLAC suffered a laser eye injury while adjusting a polarizing beamsplitter being used with a femtosecond Ti:sapphire laser.1 The laser parameters were 800-nm wavelength, 100-fs pulse width, 1-kHz repetition rate and 100-mW beam power. The polarizing beamsplitter, P1, was part of an optics configuration used for intensity control (Figure 1). During...

EDITORIAL
Make Nothing Happen Before I get out of bed in the morning, before I can even read the numbers on the clock, I have to put on my glasses. I wear contacts during the day, and if I want to clearly see words on my computer screen, I have to put on my reading glasses, too. But I consider myself lucky that my vision can still be corrected. Working in a laser lab – or any environment where lasers are in use –...

GREENLIGHT
Solar concentration without mirrors Mirror-free thermophotovoltaic devices could someday make a much simpler and less expensive system to concentrate sunlight. The goal is to prevent heat from escaping the thermoelectric material by using a photonic crystal – essentially, an array of precisely spaced microscopic holes in a top layer of the material. By concentrating the sunlight thermally – capturing it and...
LIGHTER SIDE
Out of the blue, into the office Working outdoors in the sunshine with blue skies and fluffy white clouds overhead – it sounds a little like heaven, doesn’t it? Except when rain falls, snow blows or wind gusts, of course. Skylights can provide much the same effect – for the top floor of a building – on a sunny day. But a new “virtual sky” ceiling lighting setup gives office workers the...
