The Matrix 1064-10-CW is used for precision applications in life science research, as well as marking applications where Q-switched lasers are not the optimal choice due to their high-pulse energies.

Coherent Inc., which develops laser technologies for commercial and scientific applications, is expanding its Matrix^™ line of diode-pumped lasers with a new model that deliver 10 W of continuous wave power at 1,064 nm.

This air-cooled laser provides an economical combination of high performance, long service life, and reliability, according to the developer. For example, the MATRIX 1064-10-CW offers a diffraction-limited, TEM₀₀ output beam (M²<1.2), high pointing stability (8 µrad/°C), excellent power stability (±2% over 8 hours) and low noise (<1% rms from 10 Hz to 100kHz).

In addition, because it uses Coherent AAA^™ pump diodes, (MTBF >40,000 hours) and Coherent’s proprietary PermAlign^™ construction ensures many thousands of hours of reliable, hands-free and maintenance-free operation.

A primary application for the MATRIX 1064-10-CW is in trapping and optical tweezers, which are widely used techniques in life sciences research. Here, the laser’s excellent beam parameters, power stability and low noise allow for consistent, fine focusing, which enables precise specimen positioning and manipulation. Plus, the near infrared wavelength fits well into the “therapeutic window” from 600 nm to 1,200 nm, thereby preventing deterioration and damage to living specimens.

The MATRIX 1064-10-CW is also useful for those marking applications where Q-switched lasers are not the optimal choice due to their high-pulse energies. Examples of this are fine and micro-black marking of metals including steel and titanium, as well as thin coating removal.
