Pneumatically Actuated Laser Shutters

These shutters are based on translating mirrors that direct the laser beam to a beam dump, preventing it from propagating and protecting down-beam components and personnel. A pneumatic actuator moves the mirror into or out of the beam. By storing energy as compressed air, reliable, fast and fail-safe closing is
uaranteed, even when mounted horizontally.

Features

Pneumatically actuated
In-air and UHV compatible options available
Versions for large beam diameters ( >20cm ), high intensity (PW-class) and high average power (kW)
Rapid closing times even for large mirror masses
Constructed mainly from off-the-shelf industrial, high-reliability components
Lifetime tested to > 10000 cycles
Numerous models developed for different applications
High reliability closing even in a horizontal orientation

Benefits

Simple, high-reliability control with compressed air
Adaptable design for demanding physics applications
Suitable for integration into large laser systems
No need to rely on small shutters in the front-end – laser amplifiers can stay thermalized while waiting for user operations
Certain models designed to achieve Safety Integrity Level (SIL) 3 according to IEC-61508
Reliability and availability proved from daily use at ELI Beamlines
Adaptable to demanding end-user requirements
No need for vertical gravity close in locations with space constraints

Specifications

Beam clear aperture From 50 mm to 500 mm
Opening and closing times From 50 ms to 5 seconds
Safety rating SIL2 (single shutter) and SIL3 (dual shutter)
Average laser power Up to 1 kW (with integrated water-cooled beam dump)
