I was wondering how suitable the TI DMD's are for the optical trapping of ultra-cold atoms. I want to be able to control the trapping frequency more and I want to use the DMD for better wavefront modulation to achieve this.
We use a 1069 nm laser of ~5 W for this. I've checked the SPIE digital library and it seems to be fairly unique in the world. Most people use Liquid Crystal SLMs, but these are unsuited for us since their damage threshold is at around 1 W, so we would fry the LC-SLM if we used that. So, my questions are as following:
1) How wel suited are the TI DMD's (DLP5500/D4100 or other models) to your knowledge for this application? What are properties I should consider?
2) What is the difference between the DLP5500 and the D4100?
2) Is the infrared wavelength of the light a problem? How high is the reflectivity?
3) Is the the power of the laser a problem? If so, what are the damage thresholds?
4) The TI DMD's have been primarily designed for visible light. Are there any problems, except the reflectivity, that also arise when using the TI DMD's?
5) Is there anything more that I should consider or should know?
