研究目的
Investigating the performance of a pulse-diode-intermittent-pumped 2-micron acousto-optically Q-switched Tm:YAG laser to improve output energy and ensure operation repetition.
研究成果
The pulse-diode-intermittent-pumped technology effectively relieves the thermal effect of the Tm:YAG crystal and improves output energy while ensuring operation repetition. The laser achieves a maximum output pulse energy of 6.83 mJ and a minimum pulse width of 367.7 ns at a repetition rate of 200 Hz, with a wavelength of 2014.9 nm and high stability.
研究不足
The study notes the need for optimizing the resonator design to improve stability and obtain higher output pulse energy. Additionally, coat-damage of the laser crystal is observed, suggesting the need for higher damage threshold coatings or mode expansion.
1：Experimental Design and Method Selection:
The study employs a pulse-diode-intermittent-pumped technology to relieve the thermal effect of the crystal, using two fiber-coupled pulsed laser diodes, a Q-switch, and two laser crystals in a 'V'-shape resonator.
2：Sample Selection and Data Sources:
Two composite Tm:YAG rods with a doping concentration of
3：5 at.% are used as the gain medium. List of Experimental Equipment and Materials:
Includes fiber-coupled pulsed laser diodes, composite Tm:YAG rods, acousto-optical Q-switch, and various mirrors and lenses.
4：Experimental Procedures and Operational Workflow:
The experiment involves pumping two Tm:YAG crystals intermittently with two laser diodes and triggering the Q-switch at specific times to achieve Q-switched operation.
5：Data Analysis Methods:
Output energy, pulse width, wavelength, and beam quality are measured using an energy meter, oscilloscope, spectrometer, and beam quality analyzer.
