In addition to the right hardware, the right

software is also required for optimum control of

your beam position.

In the BAM software module, not only can the

correction of the beam position be activated

and monitored, but the beam position can also

be adjusted manually.

Due to the camera-based mode of operation

of the BAM, the software determines numerous

other beam parameters in addition to the position

of the laser beam on the camera:

• Rotation

• Ellipticity

• FWHM diameter

• 1/e² Diameter

Application examples

Expandability

Separate control of different wavelengths and installation of

several beam layers per system possible.

Beam encapsulation

Compatibility with the Pulsar Tube System and connection

option for gas or positive pressure flushing guarantee

dust-free operation.

Modular system

Modular system compatible with different application scenarios,

also for use on optical table.

Beam Alignment Module

The Beam Alignment Module (BAM) from Pulsar

Photonics is a modular solution for active beam

position stabilization. Effects on the beam

position due to e.g. pointing errors and thermal

effects of laser sources or fluctuations of the

ambient temperature can be measured and

actively compensated. Thus, constant process

results are possible even under fluctuating

conditions.

Due to its modular design, the BAM can be flexi

bly adapted to different machine types, designs

and applications. Furthermore, the connection of

a gas or overpressure purge and the use of the

Pulsar Tube System can guarantee a high degree

of dust-free operation, making the module suita

ble for laser sources with high pulse energy and

high beam quality.

Dynamic beam shaping system

Beam shape on demand

The FlexibleBeamShaper (FBS) is a machine integrable

beam shaping system for laser micromachining, that can

generate any user defined beam distributions.

To achieve this, the FBS is equipped with an electronically

controllable optical phase modulator. This allows the FBS

to be used as a photonic tool magazine with predefined

beam shapes on demand. In addition, the FBS is equipped

with a SCANLAB galvanometer scanner, so the generated

intensity distribution can be scanned over the workpiece.

These tools combined in a single system open up new

ways in laser  micromaching:

faster, more flexible and more efficient.

Massive process acceleration through parallel machining

The unique combination of a precise galvano metric scanning

system and beam splitting in one system allows to multiply laser

cutting, drilling or ablation processes without loosing the freedom

of geometry of the scanner. Using diffractive opticalelements (DOEs)

the incoming laser beam is split up into multiple beams, generating

multiple laser spots in the work plane of the scanning system.

This way multpile structures can be processed in parallel or,

for example, complex cut patterns can be realized while multiplying

the production output. The MultiBeamScanner is the solution to

significatly reduce production costs in laser micromachining of periodic

structures by up to two orders of magnitude.

Extend your laser machine with a High-NA scanning solution

With the Microscan Extension MSE, Pulsar Photonics offers a simple but powerful extension for

any galvo scanning system. By simply exchanging a conventional scan lens with the MSE-G2. the

user can convert his machine to a micro spot scanning system. The combination of galvanometer

scanner and MSE-G2 allows high-precision processing with a focus diameter of less than 4μm.

This enables the production of the smallest components with unmatched accuracy and level of
