Coherent has expanded its Matrix series of diode-pumped, solid-state lasers with a new model that delivers 10W of continuous wave power at 1,064nm. This economical, air-cooled laser provides a combination of high performance, exceptional lifetime and outstanding reliability.
The model offers a diffraction limited, TEM00 output beam (M²<1.2), high pointing stability (8µrad/°C), excellent power stability (±2 per cent over eight hours) and low noise (<1 per cent rms from 10Hz to 100kHz).
A primary application for the Matrix 1064-10-CW is in trapping and optical tweezers, which are techniques widely used in conjunction with microscope systems 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 600nm to 1,200nm, thereby preventing deterioration and damage to living specimens.
The system 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.
