1：Experimental Design and Method Selection:

The study uses a laser-diode dual-end-pumped electro-optic Q-switched slab Tm:YAP laser setup. The Tm:YAP slab crystal cut by c-axis is used as the laser gain medium, and the RbTiOPO4(RTP) crystal is selected as the electro-optic Q-switched crystal. Volume Bragg gratings (VBG) are chosen as the input mirror to narrow the output line width.

2：Sample Selection and Data Sources:

The dimensions and the doping concentration of c-cut Tm:YAP crystal is 2 × 6 × 15 mm3 and 2.5at.%. The pumping source is a laser-diode with a center wavelength of 795 nm.

3：5at.%. The pumping source is a laser-diode with a center wavelength of 795 nm. List of Experimental Equipment and Materials:

3. List of Experimental Equipment and Materials: Two fiber-coupled LDs with fiber core diameter of 400 μm and numerical aperture of 0.22 are used as the pumping sources. An electro-optic Q-switch with two RTP crystals, each of the RTP crystals dimensions is 2 mm × 2 mm × 12 mm.

4：22 are used as the pumping sources. An electro-optic Q-switch with two RTP crystals, each of the RTP crystals dimensions is 2 mm × 2 mm × 12 mm. Experimental Procedures and Operational Workflow:

4. Experimental Procedures and Operational Workflow: The crystal is wrapped with indium foil and put into the micro-channel heat sink, of which the temperature is maintained at 289 K by a water cooler. 'L' -type resonator with a length of 150 mm is used.

5：Data Analysis Methods:

The output power, pulse width, and wavelength were measured using specific instruments like a high-speed silicon photodiode and a digital oscilloscope.
