Buying Terahertz Sources
Terahertz radiation can be generated using various methods, including certain gas lasers, high-frequency microwave technology, free-electron lasers, synchrotrons, difference frequency generation, optical rectification in nonlinear crystals, and photoconductive switches. These sources are essential for applications requiring terahertz waves.
Making Good Purchase Decisions
As the most professional photonics purchasing portal, RP Photonics helps you to not only to find all relevant suppliers (not limited to our advertisers), but also to make good purchasing decisions.
NEW: Structured Decision Process
Purchasing involves a lot of responsibility. We recommend that you apply best practice by using the following structured process: Go through the following expandable sections, complete the form and finally come to a purchase decision. You can then print that to a PDF for documenting the process.
Our article on best practices for purchasing and another one explaining this tool give you valuable insights.
