Summary
We developed a bismuth-doped fiber laser system producing 28 picosecond pulses at 1177 nm. Frequency doubling this output created a visible picosecond pulsed source at 588.5 nm.
Area of Science:
- Laser Physics
- Fiber Optics
- Nonlinear Optics
Background:
- Development of compact, high-power pulsed fiber laser systems is crucial for various applications.
- Picosecond pulsed sources are essential for high-resolution imaging and spectroscopy.
- Visible light sources are highly desirable for many scientific and industrial applications.
Purpose of the Study:
- To develop a bismuth-doped fiber master oscillator power fiber amplifier (MOFPA) system.
- To achieve efficient frequency doubling of the generated infrared pulses into the visible spectrum.
- To characterize the performance of the developed picosecond pulsed visible source.
Main Methods:
- Utilized a bismuth-doped fiber MOFPA system operating at 1177 nm.
- Generated 28 picosecond pulses at a 9.11 MHz repetition rate.
- Employed frequency doubling techniques to convert 1177 nm output to the visible range.
Main Results:
- Achieved 150 mW average output power and 580 W peak pulse power at 1177 nm.
- Successfully generated a visible picosecond pulsed source at 588.5 nm.
- Obtained a maximum average output power of 13.7 mW for the visible source.
Conclusions:
- Demonstrated a versatile bismuth-doped fiber laser system for generating picosecond pulses.
- Successfully developed a novel visible picosecond pulsed source via frequency doubling.
- The developed system offers a compact and efficient solution for visible picosecond light generation.
