Our History
The "Laser Technologies Center " (LLC
"LTC"),
incorporated
in
2004,
was
reorganized from CJSC "Center of Laser
Technology" based at the Department of
"Welding and Laser Technology" of St.
Petersburg State Polytechnic University
that has been operating at the laser
market since 1988.
Our main areas of activities are design,
production and sale of laser processing
equipment
and
technologies
for
engraving and welding of a wide range of
materials. We also provide a broad range
of services in treatment of a variety of
materials, production of advertisement
and
branding
products,
supply
promotional gifts, etc.

Laser Systems of Fmark Series
(hereinafter referred to as LK
FMark) based on a fiber laser are
designed for precision marking and
engraving of a wide range of
materials. All systems are supplied
with powerful software designed
by LLC "LTC".

Software
The innovation designed by our specialists is original software
for Laser Systems Management A-Script
Basic set of A-Script functions :
• work with complex units, such as a combination of text, polygons, operators,
numbers, primitives,
• use any font (both true type, and linewise)
• preview expected results of marking
• change and combine process parameters,
• free from use of other graphics and CAD-systems
• arithmetic and logical operations with vector objects,
• user data feedback
• shading and filling objects with other objects,
• support of linear and two-dimensional barcodes.

Areas of application
of laser marking
Main areas of application:
- speed marking of serial products;
- precision (high-accuracy) metals
marking;
- counterfeit protection;
- manufacturing of plate names/
control panels / stickers;
- branding of products;
- deep engraving of metals (for
further finishing);
- color marking of metals;
- high quality marking of materials
in microelectronics.

Operation diagram of the system
The method of laser marking is based
on the fact that laser radiation has a
very high power density when it is
focused into a dot with a small
diameter.
In case of metals laser marking there
are three main types of interaction of
laser radiation with a material
1. Melting
2. Intense evaporation (boiling)
3. Creation
of
high-temperature
plasma

Key Characteristics
Ensures:
- High-precision treatment ( diameter of 30
microns);
- marking materials for microelectronics, without
surface layer damage;
- Possibility of a metals contrasting color marking.
Ensures:
- Possibility of relief engraving
- Possibility of engraving curved surfaces;
- High-quality engraving of materials with high
reflectivity
- Possibility of scribing materials
- Increased performance
Ensures:
- Quality deep-etched engraving of metals (with
finishing to follow);
- Increased performance by a more powerful
laser.
Innovations in design
A unique software A-Script allows you to solve efficiently a number of tasks that
previously were beyond the control of laser technologies.
Technology for creating a "true- bitmap"
image allows to control the impact of
laser radiation applied to any dot of the
marked image, which contributes to
having a grayscale image (bitmap
mode). That means, changing the
number of pulses, we change the
contrast of each dot, which allows for
high quality of the marked images.
Innovations of A-Script:
- A selection of unique technological modes of marking
- ability to adapt software for customized problems of our clients;
- Additional applications available;
- a technology of bidirectional making with a rotator, etc

Metals and alloys
In Russian the analogue of LK FMark is a laser engraver MiniMarker manufactured
by "Laser Center" (SPb). From the comparative table you can see that LK FMark
surpasses its analog equipment by the most of its functional characteristics.

Comparison of different methods of
marking
Comparative analysis of the technical and economic characteristics of different
methods of marking was carried out through the example of serial marking of
plastic parts with size no larger than 70h90h50 mm, amount of parts not less than
1000 pcs.
