Continuous Wave and Pulsed Modes of Operation of a High Power 2.09 µm Monolithic Single Oscillator Tm3+, Ho3+- Codoped Fiber Laser

International audienceWe report on a high power monolithic single-oscillator Tm 3+ , Ho 3+ -codoped polarization maintaining fiber laser emitting at 2.09 µm in Continuous Wave and pulsed modes of operation by Q-switching the laser cavity

55 W actively q-switched single oscillator Tm3+, Ho3+-codoped silica polarization maintaining 2.09 µm fiber laser

A 793 nm diode-pumped actively Q-switched Tm3+, Ho3+-codoped PM 2.09 ?m fiber laser emitting 55 W of average power with 100 ns pulse width and 200 kHz repetition rate is reported. End-caps spliced on fiber tips enable laser power scaling with good power stability and beam quality factors (M2 < 1.7)

FBG reflected wavelength and fiber gain matching on a continuous wave monolithic Tm3+^{3+} , Ho3+^{3+} -doped fiber laser

International audienceWe present the optimization of a 2 µm CW monolithic single-oscillator laser in terms of output power and efficiency by the adaptation of the FBG reflected wavelength to the maximum gain wavelength of the fiber
