● Cavity thermal stabilization technology + thermal isolation technology， ensure long-term stability of laser power.

The Problems We Solved

Laser Thermal Effect

  • Thermal Lensing
  • Thermal Diffraction Loss
  • Thermal Rupture
  • Effect of High Temperature on Laser Performance of Crystal

Reasonable mode matching ensures perfect beam quality;

The wavelength-locked resonant pumping technology fundamentally solves the thermal effect of the laser;

Using a fully new resonant cavity configuration, the optical path is more stable;

The following is a comparison between the traditional technical solution and the Maiman technical solution

1.Resonant pumping effectively reduces the thermal effect of the laser

Resonant Pumping

Traditional Pumping

Theory and practice show that the resonant pumping technology can effectively improve the quantum efficiency and reduce the thermal effect of the laser.

2.Fully new cavity configuration improves the stability of the optical path

(1) Beams change through thermal lens in Maiman laser cavity configuration

(2) Beams change through thermal lens in traditional method

Through the rational design of the resonating cavity, the beam pointing stability is ensured, and the rate of change of the light spot with the thermal lens effect is reduced.

3.The triple frequency crystal damage was analyzed, and an effective solution to the crystal damage was proposed

Triple Frequency Crystal Damage

  • Wavelength effect of crystal damage
  • Multi-pulse Fatigue Effect of Crystal Damage
  • Anisotropy of damage threshold
  • Light absorption damage due to pollution

Resonant cavity optimization + active cleaning process + de-metallized UV light isolation technology has solved the problem of triple frequency crystal damage

Through the improvement of the process, the damage problem of the triple frequency crystal is effectively solved, and the life and stability of the ultraviolet laser are improved.

4.Optimizing the resonating cavity and the mechanical structure of the cavity to make the laser more stable

Misalignment and long-term stability of optical path

  • Asymmetric structure increases light path sensitivity
  • Optical path misalignment sensitivity
  • Light path relief due to material deformation
  • Influence of Temperature Control Accuracy on Power Stability

Resonating cavity thermal stabilization technology + resonating cavity thermal isolation technology + material processing technology ensure the long-term stability of the laser

Through the improvement of the process, the damage problem of the triple frequency crystal is effectively solved, and the life and stability of the ultraviolet laser are improved.
