| http://www.w3.org/ns/prov#value | - Services net revenue, which consists of extended warranty service contracts, advanced training programs, and other services, increased nominally $32,000, or 1.9% for the three months ended March 31, 2014, as compared to the same period of 2013, largely due to increased follow-on sales related to our growing laser customer base and increased sales and marketing efforts in this part of our business.
