In this research, Amplified Spontaneous Emission (ASE) spectrum characteristics for a highly Yb 3+ doped glass fiber with different pump powers and pump wavelengths are scrutinized. ASE spectral profile and wavelength shift corresponding to different optical fiber lengths are measured. Highly-doped Yb 3+ fiber lasers in a linear-cavity are both experimentally and analytically investigated. Rate equations are solved using quasi-numerical models. Numerical results are reported for wide range of operating conditions to enable design optimization. The model takes into account the scattering loss and the distributed laser loss power density in strongly pump condition. The effects of various parameters such as pump power, pump wavelength, signal wavelength and fiber length on the output power and laser threshold are studied. Theoretical results are shown to be in good agreement with the experimental data.

“…Recently, single frequency Erbium doped fiber lasers (EDFLs) have been shown to be capable of providing mode hop free lasers in the form of distributed feed back (DFB), distributed Bragg reflector (DBR) and ring lasers [8][9][10][11][12][13][14][15]. Many works have also been reported on Q switched and mode locked fiber lasers [16][17][18].…”

A tunable laser is demonstrated using a microfiber knot resonator structure made by erbium doped fiber (EDF). The laser is made of a 2 m long EDF where 30 mm of its end section is tapered to con struct a microfiber knot resonator (MKR). The combination of the EDF and MKR generates a stable single wavelength laser at 1555 nm wavelength with a signal to noise ratio (SNR) of 33.7 dB using a 63 mW of 980 nm pump power. The peak wavelength of the laser can be tuned by 340 pm as the MKR diameter reduces from 5.0 to 0.5 mm with an acceptable penalty in output power.

“…Yb doped fiber lasers (YDFL) have attracted intensive attention due to its capability in high level output power with good conversion efficiency [1][2][3][4][5][6][7][8][9][10][11]. According to the oscillation spectral range of YDFL, they could be divided into three bands: convenient band (C band) that corresponds to the widely used 1060-1130 nm range, short band (S band) that corre sponds to the 975-980 nm and 1020-1060 nm range, long band (L band) that corresponds to the wave lengths longer than 1130 nm [12].…”
