Title: 12W laser amplification at 1427nm on the ⁴F_3/2 to ⁴I_13/2 spectral line in an Nd³⁺ doped fused silica optical fiber

Abstract

A 9.3dB improvement in optical gain and a 100x improvement in total optical power over prior published experimental results from the ⁴F_3/2 to ⁴I_13/2 transition in an Nd³⁺ doped fused silica optical fiber is demonstrated. This is enabled via an optical fiber waveguide design that creates high spectral attenuation in the 1050-1120nm-wavelength range, a continuous spectral filter for the primary ⁴F_3/2 to ⁴I_11/2 optical transition. A maximum output power at 1427nm of 1.2W was attained for 43mW coupled seed laser power and 22.2W of coupled pump diode laser power at 880nm a net optical gain of 14.5dB. Reducing the coupled seed laser power to 2.5mW enabled the system to attain 19.3dB of gain for 16.5W of coupled pump power. Four issues limited results; non-optimal seed laser wavelength, amplified spontaneous emission on the ⁴F_3/2 to ⁴I_9/2 optical transition, low absorption of pump light from the cladding and high spectral attenuation in the 1350-1450nm range. Lastly, future fibers that mitigate these issues should lead to significant improvements in the efficiency of the laser amplifier, though the shorter wavelength region of the transition from 1310nm to >1350nm is still expected to be limited by excited state absorption.

Efficient 2-Micron Laser Driver for Laser Acceleration

Technical Report Vetrovec, John

Laser acceleration of nuclear particles is an emerging technology aimed to supplant the traditional radio-frequency (RF) accelerators while offering several orders of magnitude reduction in size and cost. Although laser acceleration has been demonstrated in 1990's and it is now pursued worldwide, production of particle currents comparable to RF accelerators is impeded by the lack of a powerful, efficient, and economical laser acceleration driver (LAD). Today’s LADs operate only at few hertz (Hz) pulse repetition frequency (PRF) because of the waste heat deposited into the laser gain material (LGM). To attain pulse frequencies in the targeted kilohertz or even megahertzmore »« less
Analysis of erbium-doped fiber amplifiers pumped in the /sup 4/I/sub 15/2/-/sup 4/I/sub 13/2/ band

Journal Article Desurvire, E - IEEE Photonics Technology Letters; (USA)

In this paper a theoretical model for Er/sup 3+/ -doped fiber amplifiers pumped within the particular /sup 4/I/sub 13/2/ /sup 4/I/sub 15/2/ absorption band is developed. The model predicts gain coefficients around 2 dB per milliwatt of launched pump power, in close agreement with previously reported measurements. The model is also used to determine the optimal pump wavelength {lambda}/sub opt/ that maximizes the amplifier gain. It is shown that the latter is insensitive to pump detuning near {lambda}/sub opt/ = 1.48 {mu}m, within a 20 nm range, which indicates that broad-band, multimode laser diode pump sources and pumps with narrowmore »« less

Scalable waveguide design for three-level operation in Neodymium doped fiber laser

Journal Article Pax, Paul H. ; Khitrov, Victor V. ; Drachenberg, Derrek R. ; ... - Optics Express

We have constructed a double clad neodymium doped fiber laser operating on the three-level ⁴F_3/2 → ⁴I_9/2 transition. The laser has produced 11.5 W at 925 nm with 55% slope efficiency when pumped at 808 nm, comparable to the best previous results for a double-clad fiber configuration on this transition. Higher power pumping with both 808 nm and 880 nm sources resulted in an output of 27 W, albeit at lower slope efficiency. In both cases, output power was limited by available pump, indicating the potential for further power scaling. To suppress the stronger four-level ⁴F_3/2 → ⁴I_11/2 transition wemore »« less

High Energy Laser for Space Debris Removal

Technical Report Barty, C ; Caird, J ; Erlandson, A ; ...

The National Ignition Facility (NIF) and Photon Science Directorate at Lawrence Livermore National Laboratory (LLNL) has substantial relevant experience in the construction of high energy lasers, and more recently in the development of advanced high average power solid state lasers. We are currently developing new concepts for advanced solid state laser drivers for the Laser Inertial Fusion Energy (LIFE) application, and other high average power laser applications that could become central technologies for use in space debris removal. The debris population most readily addressed by our laser technology is that of 0.1-10 cm sized debris in low earth orbit (LEO).more »« less

Optimal pump wavelength in the sup 4 I sub 15/2 - sup 4 I sub 13/2 absorption band for effieciet Er sup 3 sup + -doped fiber amplifiers

Journal Article Zyskind, J L ; Giles, C R ; Desurvire, E ; ... - IEEE Photonics Technology Letters (Institute of Electrical and Electronics Engineers); (USA)

The gain of a highly efficient erbium-doped fiber amplifier was measured when pumped at wavelengths between 1.46 and 1.51 {mu}m. The optical pump wavelength {lambda} was determined to be 1.475 {mu}m. At this pump wavelength, the maximum gain coefficients for signals at 1.531 and 1.544 {mu} were measured to be 2.3 and 2.6 dB/mW, respectively. At {lambda},{sup opt{sub p}} high gains were achieved, ranging from 32 dB at pump power P{sup in{sub p}} = 20 mW up to 40 dB at P{sup in{sub p}} = 80 mW.
