Request Info

Intense Inc. has released a 300-mW version of its Series 6030 and Series 6130 ultrahigh-power, high-brightness single-mode laser diodes. Designed for defense, medical and print/imaging applications such as spectroscopy and industrial coding, the diodes are available in 980-, 830-, 808-, 785- and 780-nm wavelengths. Custom packaging and wavelengths are available upon request.

Part of the company’s Series 6000 family of single-mode lasers, the new models are based on the proprietary and patented Quantum Well Intermixing technology, which increases the brightness and reliability of laser diodes while avoiding the usual problems associated with catastrophic optical mirror damage.

Until now, 300 mW of true single-mode power hasn’t been available, particularly in the shorter wavelengths of 808 to 830 and 780 to 785 nm. These new wavelengths and ultrahigh power offerings are driving new uses, particularly in illumination, spectroscopy, life sciences and atomic clock applications.

The Series 6030 and 6130 offer high electrical conversion efficiency in a range of operating temperatures from 25 to 50 °C. The lasers are available in a selection of free-space packages, including 9-mm, C-mount and 5.6-mm, with pulse duration modulation optional. Multi-emitter, individually addressable, custom ultrahigh-power arrays have also been designed using the basic 6030 design.

Intense offers the Series 6030 and 6130 single emitters in a variety of standard beam divergences to match specific application requirements. Multiple FAC lensing options are also available.

The company also can fabricate ultrahigh-power, single-mode, individually addressable multichannel arrays in wavelengths ranging from 650 to 980 nm with 10 to 270 channels per array. Arrays can be integrated with full drive electronics and both micro and macro lens options.
