Big translation stage have been delivered. The company man came last thursday and today. We temporary mounted the parts on a small optical table, we configured the controllers using its software. It works properly.

Next steps before setting the big translation stage are:

 - To measure the absorption of the two Shinkousha sapphire samples that Hirose-san kindly sent to us. 

 - To make some power measurements of the pump (after and before the chopper), in order to see how the power measurement depends on the modulation frequency.

 - To understand better the beam profile of the probe beam in order to be able to make a detail design of how to move the parts of the absorption system and make enough space to place the big mirrors.
