  • Matrix CW DPSS Laser
Jun 2011
Coherent Inc.Request Info
SANTA CLARA, Calif., June 10, 2011 — Coherent Inc. has expanded its Matrix series of diode-pumped solid-state (DPSS) lasers with a new model that delivers 10 W of continuous-wave power at 1064 nm.

The air-cooled laser combines high performance, long lifetime and reliability. The Matrix 1064-10-CW offers a diffraction-limited TEM00 output beam with M2 <1.2, pointing stability of 8 µrad/°C, power stability of ±2% over 8 h and low noise of <1% rms from 10 Hz to 100 kHz. Proprietary AAA pump diodes, with a mean time between failures of >40,000 h, and the company’s PermAlign construction technology guarantee reliable, hands-free and maintenance-free operation over tens of thousands of hours.

Primary applications are in trapping and optical tweezers, techniques widely used in conjunction with microscope systems in life sciences research. Here, the laser’s beam parameters, power stability and low noise allow for consistent fine focusing, which enables precise specimen positioning and manipulation. And the near-infrared wavelength fits well into the “therapeutic window” from 600 to 1200 nm, preventing deterioration and damage to living specimens.

The laser is also used for marking applications where Q-switched lasers are not the optimal choice because of their high pulse energies. Examples of this are fine and microblack marking of metals including steel and titanium, as well as thin coating removal.
