Description
Technical Field
The invention relates to the technical field of lasers, in particular to a 589nm laser with a compact structure.
Background
The high-power single-frequency 589nm laser has important application requirements in the fields of sodium star guide, laser radar, laser medical treatment and the like. These fields of application are very high for the specific wavelength and power requirements of the laser, which are exactly met by the high power single frequency 589nm laser.
In the sodium satellite guide aspect, high-power single-frequency 589nm laser is widely used in adaptive optics systems. When high-power single-frequency 589nm laser is emitted from the earth atmosphere, the high-power single-frequency 589nm laser interacts with sodium atoms in the atmosphere to form an artificial star with observable signals. The artificial star can be used for calibrating a telescope, improving the quality of astronomical observation images, carrying out atmospheric research and the like.
Secondly, high-power 589nm laser has important application requirements in the field of laser radars. Lidar requires a stable, narrow linewidth laser beam for distance measurement and target identification. The 589nm wavelength laser has good photoelectric conversion efficiency and lower scattering loss, and has longer transmission distance in the atmosphere.
In laser medical applications, such as macular degeneration treatment, glaucoma treatment, minimally invasive surgery, 589nm lasers are widely used in a variety of ophthalmic minimally invasive surgery, such as myopia laser surgery (LASIK, PRK, etc.), cataract extraction, etc. The single frequency nature of such lasers enables more accurate localization and treatment of ocular tissue, thereby minimizing damage to surrounding tissue.
At present, most star-guiding lasers are based on sum frequency generation of 1064nm and 1319nm solid lasers or second harmonic generation of 1178nm Raman fiber amplifiers, and most of the star-guiding lasers are formed by respectively generating two different wavelengths by two discrete laser crystals and then performing sum frequency by a nonlinear crystal; or a laser crystal dual-wavelength operation is adopted and then the operation passes through the nonlinear crystal cavity to sum the frequency, the structure is generally complex, or the conversion efficiency is lower, and when the mode of combining the 1178nm single-frequency Raman fiber laser amplifier and frequency multiplication is adopted, the output power of the single-frequency amplifier can be limited due to the stimulated Brillouin scattering effect.
