  • Cube 445 Laser

Coherent Inc.Request Info
SANTA CLARA, Calif., Oct. 12, 2006 -- The new Cube 445 from Coherent Inc. is a compact, conduction-cooled laser that delivers 40 mW of power at 445 nm. Thanks to its all-semiconductor technology, the Cube 445 delivers higher reliability, lower noise and longer lifetime than HeCd (helium-cadmium) gas lasers, which were formerly the only choice at this wavelength, the company said.

CUBE445.jpgThe Cube 445 also offers superior beam characteristics compared to HeCd lasers, with an M2 of typically less than 1.2, a beam divergence of 0.6 mrad, a pointing stability of under 6 µrad/°C, and a typical RMS noise level of 0.05 percent (20 Hz to 100 MHz). Plus, the laser head measures only 100 x 40 x 40 mm (3.9 x 1.6 x 1.6 in.) and dissipates typically 3 W of heat.

The superior mechanical, optical and thermal characteristics of the Cube 445 will make it particularly attractive to OEM system builders, Coherent said. Cube 445 also streamlines the process of system design, because it can be directly modulated (analog or digital) at bandwidths of up to 125 MHz. Interface to the laser is through standard USB and RS-232 with full control and measurements. Simplifying the design of multiwavelength systems, the Cube 445 shares the same form factor as Cube lasers at other wavelengths.

Applications for the Cube 445 laser include biomedicine, microelectronics and engineering prototyping for semiconductor inspection, flow cytometry, confocal microscopy and stereolithography.

1. A bundle of light rays that may be parallel, converging or diverging. 2. A concentrated, unidirectional stream of particles. 3. A concentrated, unidirectional flow of electromagnetic waves.
A method of creating real three-dimensional models by using lasers driven by CAD software. In contrast to the normal practice of removing material, this process polymerizes a liquid to quickly produce shapes that are untouched by human hands or cutting tools. Also known as three-dimensional imaging and three-dimensional modeling.
