Scanlab Beam Alignment Module – BAM-G1

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.

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.
