How to fill out rare-earth doped phosphate-glass lasers

How to fill out rare-earth doped phosphate-glass lasers:

1. Prepare the rare-earth doped phosphate-glass laser material by cleaning the optical surfaces and ensuring they are free from any contaminants.
2. Mix the rare-earth dopant into the phosphate-glass matrix in the desired concentration. This is usually done by melting the glass and adding the dopant material.
3. Mold the glass into the desired laser shape, such as a rod or a disk, using conventional glass shaping techniques.
4. Polish the laser surface to achieve the required optical quality and smoothness. This step is crucial for maximizing laser efficiency and reducing parasitic losses.
5. Assemble the laser cavity by placing the rare-earth doped phosphate-glass laser material between two mirrors or optical elements that allow light reflection and amplification within the laser medium.
6. Align the mirrors or optical elements to ensure proper beam path and resonant mode in the laser cavity.
7. Provide a proper excitation source, such as a laser diode or flashlamp, to pump energy into the rare-earth ions within the laser material and enable population inversion.
8. Optimize the laser parameters, such as pump power, cavity length, and coupling efficiency, to achieve desired laser performance, such as output power, wavelength, and beam quality.
