Research for better metal engraving tool using 1064 – 1080 nm DPSSL laser modules (detailed research)

Research for better metal engraving tool using 1064 - 1080 nm DPSSL laser modules (detailed research)

A lot of our customers and potential customers would like to engrave on steel, copper, brass, aluminum and other alloys with no paste.
Right now you may use Cermark paste or Dry Lube Moly with MoS2.

We have started research looking for the best tool that can be used for that.
We are looking for a laser module that will fit our requirements.

Our first research showed us that CW lasers with 10-30 watt laser power output are not good for that.
Metal engraving requires pulsed energy being aimed in one spot – then the energy reaches kWatts.
When the energy has a very short pulse in nanoseconds for example then we use this equation:

The power P in watts (W) is equal to the energy E in joules (J), divided by the time period t in seconds (s):
P(W) = E(J) / t(s)

that is why when the impulse is very short we get the energy much higher during that impulse. That is why most DSPP lasers have kW of energy power output.

At the moment we have got a few offers from different laser suppliers.

Datailed manual of FL-1064 with 2 signal lines(EN)

Manual of how to manufacture the marking machine with FL-1064

We looked, we studied the CNI proposal (it is identical to the Laserglow, which, most likely, it is simply resold).

It is clear that this laser has: a 50 watt or 100 watt laser line for pumping, an optical modulator, a second-harmonic conversion crystal, its cooling, and the driver of the laser itself. Among other things, there are doubts how effective the marking on metal can work on 5-10 watt. Usually, at such power, plastic is labeled. Metal marking starts from 30-50W, or the metal should be just black.

The smallest laser beam at focus point is about 57um,
Best focus length (working distance) is about 80mm.

These parameters are good for us.

Test report of 1064-10W
was made specially for Endurance lasers.

2. BWT Beijing, Ltd.

2.1. 976nm/10W, 105um/0.22NA,
This LD has the 200cm±10cm fiber

976 nm laser diode

2.2. 1064nm wavelength laser diode.
Actually, this is the detachable output mode LD, usually, it used in the medical application.

1064 Nm laser diode

Not likely that CW modules with this wavelength would wor for us.

3. Laserglow

(it is very likely that these guys do not produce laser modules but resell from CNILasers)
