Efficient Single-Frequency Thulium Doped Fiber Laser Near 2-μm
We demonstrate highly efficient diode-pumped single-frequency fiber laser with 35% slope efficiency and 50mW output power operating near 2μm, which generated from a 2-cm long piece of highly Tm-doped germanate glass fiber pumped at 800nm. ©2007 Optical Society of America OCIS code: (060.2320) Fiber optics amplifiers and oscillators; (140.3570) Lasers, single-mode; (140.5680) Rare earth and tran...

متن کاملHigh average power picosecond pulse generation from a thulium-doped all-fiber MOPA system.
We report a stable highly-integrated high power picosecond thulium-doped all-fiber MOPA system without using conventional chirped pulse amplification technique. The master oscillator was passively mode-locked by a SESAM to generate average power of 15 mW at a fundamental repetition rate of 103 MHz in a short linear cavity, and a uniform narrow bandwidth FBG is employed to stabilize the passivel...
متن کامل50-W 2-μm Nanosecond All-Fiber-Based Thulium-Doped Fiber Amplifier
We report a two-stage 2-μm Tm3+ fiber amplifier seeded by an acousto-optic modulator (AOM) modulated narrowbandwidth pulsed laser. Maximum output average power is over 50 W (slope efficiency of ∼58%) at 50 kHz repetition rate, providing record performance in nanosecond 2-μm all-fiber-based amplifiers. The maximum pulse energy and peak power are ∼1.0 mJ and 10 kW, respectively. The pulse width c...
متن کاملPreparation and characterization of highly thulium- and alumina-doped optical fibers for single-frequency fiber lasers
Thulium-doped fibers suitable for core-pumped single-frequency lasers were fabricated by the modified chemical vapor deposition (MCVD) method. Refractive index profile, doping profile and spectral absorption was measured. High doping concentration of thulium ions should be achieved to allow for high absorption of light at a pump wavelength while the thulium ions clustering should be avoided to ...
