Low voltage stacks for ultrafast lasers 

 

Ultrafast lasers benefit from Noliac Motion’s 3x3 mm 60V piezoelectric stack actuators as these are ideal for compact designs requiring extremely short time scales or extremely high powers.

 

Ultrafast lasers are used in many areas such as medical and life-science diagnostics, precision measurement, sensing, optoelectronic testing, clocking and switching, frequency conversion and many other applications.

 

Piezoelectric stacked actuator

 

Smallest man-made structures 

With the aid from a small piezoelectric actuator stack, a pulsed laser concentrates its energy into brief bursts. An ultra fast laser produces fantastically short bursts in which the intensity and power of the pulses can reach mind-boggling levels.

 

Because the pulses happen so quickly, the effects are concentrated in time. This gives ultra fast lasers valuable properties that their slower predecessors do not have. They can, for instance, cut something out before the energy from the pulse gets a chance to heat up and possibly damage the surrounding area.

 

This means ultra fast lasers are better at such jobs as cutting and welding, eye surgery and creating some of the smallest man-made structures on the surface of semiconductors

 

Ring or plate stacks 

Piezoelectric plate stacks (SCMAP) can be made down to 3x3 mm in base and with the height applicable for the specific application. Full performance is achievable down to 60V. 
 

If more force is required, piezoceramic ring stacks (SCMAR) is an excellent alternative.

 

Highlights:

SCMAP SCMAR

Square or rectangle shapes

 

Typical cross sections are 3mm x 3mm, 5mm x 5mm, 7mm x 7mm and 10mm x 10mm

 

Height can be up to 10x the smallest cross section dimension, i.e. 100mm for a 10mmx10mm cross section

 

Blocking force up to 4000N

 

Full performances achievable with voltages down to 60V

Ring shape

 

Typical sizes are OD6mm, OD8mm, OD12mm, OD15mm and OD20mm

Blocking force up to more than 8000N

 

Full performances achievable with voltages down to 200V

 

Better resistance to humidity than square shape actuators

 

Easy integration due to the ring shape
