研究目的
Investigating the use of MXene Ti3C2Tx as a saturable absorber for passively Q-switched mid-infrared laser operation in femtosecond-laser–inscribed Er:Y2O3 ceramic channel waveguides.
研究成果
The study successfully demonstrated the first Er3+-doped mid-infrared waveguide laser using MXene Ti3C2Tx as a saturable absorber, achieving significant output power and efficiency. The findings suggest MXene Ti3C2Tx's potential for mid-infrared laser applications and the effectiveness of femtosecond laser direct writing for waveguide fabrication.
研究不足
The study was limited by the available pump power, suggesting potential for power scaling with increased pump power. The modulation depth of the MXene SA was relatively small, limiting further pulse width narrowing.
1：Experimental Design and Method Selection:
The study utilized a femtosecond laser direct-writing technique to fabricate Er:Y2O3 ceramic channel waveguides. MXene Ti3C2Tx was prepared as a saturable absorber for Q-switching.
2：Sample Selection and Data Sources:
Er:Y2O3 ceramic was used as the waveguide material. MXene Ti3C2Tx nanosheets were prepared via an acid-etching process.
3：List of Experimental Equipment and Materials:
A Ti:sapphire regenerative amplifier for waveguide fabrication, MXene Ti3C2Tx nanosheets, and a 976-nm diode laser for pumping.
4：Experimental Procedures and Operational Workflow:
The waveguide was fabricated, characterized, and then tested in both continuous-wave and Q-switched regimes using the MXene saturable absorber.
5：Data Analysis Methods:
Nonlinear saturable absorption of the MXene SA was measured, and laser performance parameters were analyzed.
