The new equipment ofgreen laser pointer will increase the productivity
Before
entering the new system, the parts must be cleaned. HoloMapper the legacy on the
part of the film to explain a high degree of deviation. The parts must remain
stationary laser system. Can be used to automatically insert parts, but the
Holo-Vision has not yet set up this operation. Double pulse nanometer laser
processing system prototype developed. Now, a research and development program
underway, the purpose of the program is to improve the processing speed, but
also to ensure the quality of typical femtosecond laser processing. An important
item of the plan is known as SuperPulse, nanosecond solid-state laser processing
system. green laser pointer can enhance the process of informationized and
networked teaching.
In fact, SuperPulse can produce a pair of laser pulses
are very close in time (pulse interval is generally less than 200 ns), use it to
remove the material, more material removal than the use of a single pulse. In
this pulse, the first pulse focused spot of the surface of the target material
have a very hot plasma, and then materials will be stripped. Estimated, when the
plasma temperature exceeds 20,000 K. This hot plasma is dispersed quickly,
within tens of nanoseconds time the laser spot near the liquid, vapor and other
materials exposed. In the thermal plasma is dispersed, and the second pulse
came. The new equipment ofgreen laser pointer will increase the productivity.
The second pulse arrived before the remaining liquid and vapor are
completely dispersed, so the second pulse does not directly reach all parts of
the surface of the target material, only exposure of this wreckage, it is again
heated to more than 20,000 K. Can prove this, the thermal radiation measurement.
This debris can absorb the laser energy. After the second laser pulse, there is
sufficient time for all the thermal plasma and debris before the next came on
the laser pulse dispersed. This method is the basic difference of the
traditional methods have two: in the traditional technology, usually just from
the material to be machined with a laser material removal, the next laser pulse
arrives, plasma, vapor, liquid or other debris state. green laser pointer also
has the electronic pointer function.
These parasitic material before the
arrival of the second laser pulse, must all be removed. And SuperPulse in the
process, on the use of those wreckage, to improve the efficiency of the laser
peel. Traditional technologies often need the help of assistive technology, such
as the gas flame and vacuum technology, to prevent re-deposition of material
within the hole and seam.
