    Abstract: Methods, systems and light emitting units with light emitting diodes may be for facilitating production of vitamin D, reducing microbial pressure and optionally providing work light inside buildings. A light emitting unit is provided for reducing the microbial pressure in a building preferably in combination with sensors, and for promoting formation of natural vitamin D3 in animals and/or humans, and preferably also providing visible work light. A light emitting unit may include at least a first UV-B LED configured for emitting monochromatic UV-B light with maximum intensity between 292-302 nm, 295-299 nm, 296-298 nm, or 297 nm, and at least a second UV-B LED configured for emitting monochromatic UV-B light with maximum intensity between 278-288 nm, 281-285 nm, 282-284 nm, or 283 nm and/or at least a first UV-C LED configured for emitting monochromatic UV-C light with maximum intensity between 228-238 nm, 231-235 nm, 232-234 nm, or 233 nm.

    Abstract: The present invention provides a photon beauty mirror, comprising: a main frame, a first light source assembly, a circuit board and a special optical filter. The special optical filter comprises an optical substrate coated with a filter film of a preset wavelength bands on one side and coated with a one-way perspective film on an opposite side of the optical sheet, light of the preset wavelength bands passes through the filter film for beauty treatment; the one-way perspective film reflects visible light to obtain a mirror effect; or, comprises an optical substrate coated with a filter film, where near infrared light or non-visible light above 700 nm transmit through the filter film for beauty treat, and the filter film reflects visible to obtain a mirror effect.

    Abstract: A medical laser system including a first laser source having a first gain medium for generating a first optical field. The system further includes a first Q-switch controlling a resonance quality of the first laser source, a control circuit controlling the first Q-switch to cause the first laser source to generate the first optical field as a first pulse train of laser pulses, a second laser source for generating a second optical field as a second pulse train of laser pulses, a nonlinear medium for generating a third optical field by a nonlinear interaction between the first optical field and the second optical field, and a sensor detecting a property of at least one of the optical fields. The control circuit controls operation of the first Q-switch so as to adjust a relative timing of the laser pulses of the first pulse train and the laser pulses of the second pulse train responsive to the detected property.
