Abstract
The present invention provides an optical amplifying device which can be easily downsized, increased in output, and stabilized. An optical amplifying deviceA includes an optical amplifierA and an energy supplier. The optical amplifierA includes an optical amplifying mediumand a transparent medium. The energy suppliersupplies excitation energy (for example, excitation light) to the optical amplifying medium. The optical amplifying mediumis supplied with the excitation light to amplify light and output it. To-be-amplified light passes through the transparent mediumin the optical amplifying mediuma plurality of times. The transparent mediumcan propagate the to-be-amplified light, for example, zigzag inside.
