Abstract
- A gain-switched pulsed laser based on a commercial, heavily holmium-doped fluoroindate glass fiber, is designed to emit in the middle-infrared range, at the wavelength λ = 3.92 μm. The laser, pumped at λ = 888 nm is modeled by a six-level system, by taking into account experimental spectroscopic parameters, to identify a feasible laser configuration. An output signal peak power of about P<subscript>s</subscript><superscript>peak</superscript> = 14.62 W with a full width at half maximum (FWHM) pulse duration less than τ<subscript>s</subscript> = 73 ns and pulse energy E<subscript>s</subscript> = 1.214 μJ is predicted, by considering an input peak power of P<subscript>p</subscript><superscript>peak</superscript> = 10 W, and pump repetition rate of ƒ = 100 kHz, by employing a 8 cm-long fluoroindate fiber with holmium concentration N<subscript>Ho</subscript> = 100 000 ppm. The obtained result encourages the construction of a pulsed laser based on commercially available optical fiber, for applications in different fields as sensing and biomedicine.
