A particle filter is necessary to prevent build up of contamination and deposits within the cooling circuit and the surfaces of gold, silver and ceramic pump cavities, laser lamps, pump diodes, laser crystal flow tubes and flow plates. A particle filter can come in a large variety of shapes and pore sizes. The pore size typically ranges between 0.2 and 10 microns depending on laser model and system application. To ensure optimum laser performance and cooling circuit protection, it is recommended you change a particle filter on a regular maintenance schedule.
