Matching of Pumped and Laser Mode Volumes Inside a Diode Side-pumped Solid-state Laser

Ho Quang Quy, Mai Van Luu, Vu Ngoc Sau


The condition to match the pumped-volume's width with the laser mode-volume's waist in a diode four side pumped solid-state laser is analyzed by numeric solutions of the approximation equation. As a result, the dependences of pumped volume's width on pumping diode parameter and laser mode volume's waist on cavity parameter were found. Such a matching condition was simultaneously determined by cavity, pumping beam and laser rod parameters.
