Abstract

The search for simple and effective methods of erbium glass lasers (lasing wavelength 1.54 microns) Q-switching is a task of present interest. It is interesting because this wavelength radiation is relatively eyesafe and may be used in medicine, lidars, and fiberoptics. Nowadays, existing active methods of Q switching are rather inconvenient for practical use (rotating prism) or complex and not too efficient (electrooptic cell). As for passive shutters based on color centers in crystals, or organic dyes, nowadays they are only under development, and Q—switching is obtained in them only as a small effect. In this report, two new simple methods of passive Q-switching of erbium glass lasers are suggested, and the main properties of obtained giant pulses are investigated.
