Diode Lasers Provide High Brightness

Single-emitter units are available in a wide range of wavelengths

Multimode diode lasers are available in operating wavelengths from 635
to 1600 nm and output powers from 0.5 to 5 W, continuous wave.

A line of high-brightness, single-emitter, multimode diode lasers is C-mount packaged. The lasers from nLight (Vancouver, WA) are available in operating wavelengths from 635 to 1600 nm and output powers from 0.5 to 5 W, continuous wave (CW). The industry-standard lasers are suitable for pumping diode-pumped solid-state lasers, materials processing, and other medical applications.

“Our C-mount lasers provide not only high-power but also industry-leading brightness in a range of wavelengths from an industry-recognized package, making them ideal for integration into virtually any laser-based application,” said Merrill Apter, the company’s vice president of sales and marketing, “We are producing 25- to 30-milliwatts per micron power density. This allows us to build products that generate, from a 200-µm broad-area emitter, up to 5 W, CW at 808 nm.”

As an added feature the company can provide a fast axis-collimating lens, which allows in excess of 95% power transmission and collimates the fast axis down to <0.5 degrees, FWHM.

The company’s 5-W device has an operating current of 5000 mA; compliance voltage is 1.95 V. It features a spectral width of <2 nm, FWHM, and beam divergence of <36° by <10°, FWHM. The 0.5-W device is a 150-µm broad-area emitter at 635 nm. The 0.5-W laser features a 1000-mA operating current and compliance voltage of 2.2 V. Beam divergence is <42° by <10°, FWHM. All lasers feature high-power conversion efficiency.
