Abstract

Scaling the pulse energy and peak power in high-power, narrow-linewidth Thulium-doped fiber lasers (TDFLs) is fundamentally limited by parasitic lasing, amplified spontaneous emission (ASE), and nonlinear effects. We present a nanosecond-pulsed Tm-doped photonic crystal fiber MOPA that successfully pushes these performance boundaries, delivering 2.07 mJ nearly rectangular-shaped pulses, with 52 kW peak power at 207 W average power, linear polarization, a narrow 390 pm linewidth at 2048 nm and excellent beam quality (M²
