"We integrated the Hamamatsu LCoS SLM X10468-02 as a flexible diffractive optical element into our nanofabrication setup, where a short-pulsed high power laser beam is focussed into transparent material in order to perform local modifications of the material. The first experiments with the SLM integrated were about sensing for optical aberrations in the fabrication beam. (please see http://www.opticsinfobase.org/DirectPDFAccess/65A87C0D-BDB9-137E-C2DE1330F1450C50_194332.pdf?da=1&id=194332&seq=0 )
The SLM was used to introduce different phase distortions from which we could deduce the real aberrations in the laser beam. A particular advantage of using the SLM compared to a deformable mirror in this experiment was that it allowed us to add binary diffraction gratings to the phase distortions, which reduced the amount of time necessary to perform the aberration measurements by a factor of 2. Two other major advantages of this system in particular are its high light utilization efficiency and high power handling capability, which is of utmost importance in our case, since we use a regeneratively amplified femtosecond laser."

"The optical trapping group at St Andrews has been actively engaged in
beam shaping for a variety of applications in biophotonics over the
last decade. This has included optical trapping studies, advanced beam
propagation and cell transfection. We have been very impressed with
the LCOS range of spatial light modulators from Hamamatsu and used
them extensively in various demanding applications. They have proved
to have very good characteristics for generating a wide array of beam
profiles and we have been able to address them with appropriate
software for full user control in our experiments. We are very excited
with their future potential for various biophotonics applications."

"I am writing to tell you just how happy with have been with your LCOS, SLMs (X10468-01) in our quantum optics experiments. Their combination of high diffraction efficiency, low aberrations and ease of interfacing makes them ideal for us. Specifically we are using them to measure the spatial mode profile at the single photon level and applying this to a novel form of Ghost Imaging."

Testimonial for Hamamatsu Photonics UK Ltd.
"I would highly recommend this Company and their products to any potential collaborator or purchaser. In particular, with regard to the Spatial Light Modulator products, the X-10468 series, we have tested the NIR (-03), the visible (-04 and -01) systems with excellent results. In particular, the -03 and -04, with dielectric coatings, are able to handle high average laser powers > 3W. The products are well engineered and highly reliable and each device comes with a unique file correcting for any slight wavefront variations, important in precision work.
I have also been granted significant loan periods in order to assess the products and this was very useful in our evaluation of the potential of these devices for materials processing. We own one system and will soon acquire a second.
In short, Hamamatsu Photonics UK have been an excellent partner in our research work and I look forward to further future collaboration with them. Dr. Raymond Livingston, in particular has been very helpful and highly expert in these devices."
