There are two typical types of Er:Glass lasers,one is using laser rod as working medium,another is using bonded Er:Glass to get gain medium,Q-swith and output coupler as a whole,which present advantages of easy fixing and stable construction.There are three types of Er:Glass modules available specified as:10Hz@200uJ;10Hz@300uJ and 1000Hz@40uJ .As we know,Co:Spinel ( Co2+:MgAl2O4) ) is ideal material of passive Q-Switch for 1535nm laser, so we bond Er 3+,Yb3+:Phosphate glass and Co2+:MgAl2O together  as a whole composite laser rod,slab or any other shape as required for better structured DPSS laser by moulding,which is way for us deeply joining clients designing lasers.KITS of  crystal module,LD pump laser and collimating lens can be supplied as required.
