Example 1:
as shown in fig. 1 and fig. 2, embodiment 1 of the present invention provides a light emitting device for a laser, including a plurality of light emitting sources 1, a base 2, and a light path adjusting device 3: the light-emitting wavelengths of the light-emitting sources 1 are at least two, and the light-emitting sources 1 are arranged on the base 2; the light path adjusting device 3 is located on the light path after the light emitted from the light sources 1 is converged.
Specifically, when the light-emitting wavelengths of the light-emitting sources 1 are the same, the present embodiment can output a single-wavelength light beam that is the same as that in the prior art, but whether the light-emitting wavelengths in practical application are the same as that of the light-emitting sources 1 is not the same as that of the light-emitting sources 1, and in practical application, the switch of the partial light-emitting sources in the light-emitting sources 1 can be controlled to realize single-wavelength light-emitting or multi-wavelength light-emitting. Therefore, when the light-emitting wavelengths of the light-emitting sources 1 are different, the laser light source capable of outputting a single wavelength can be realized, and the output can be specifically adjusted according to requirements.

Further, the light path adjusting device 3 is a polygon mirror or a polygon cone mirror, such as a dodecagonal cone mirror, a hexagonal cone mirror, or a pentagonal cone mirror. The side surface of the polygon stage mirror or the polygon cone mirror forms a certain angle with the light path direction to ensure that light emitted by the light sources 1 is transmitted in the same direction after being deflected by the light path adjusting device 3, and if the light is reflected by the side surface of the light path adjusting device 3, the laser light with different wavelengths emitted by the light sources 1 is deflected by 90 degrees. In addition, the number of the polygonal pyramid mirrors or the polygonal pyramid mirror side surfaces is greater than the number of the light-emitting sources 1, or the number of the polygonal pyramid mirrors or the polygonal pyramid mirror side surfaces is less than the number of the light-emitting sources 1, or the number of the polygonal pyramid mirrors or the polygonal pyramid mirror side surfaces is equal to the number of the light-emitting sources 1. The side lengths of the polygon mirror or the polygon mirror may be the same or different, and at this time, one or more light sources 1 may be disposed at corresponding positions on each side of the polygon mirror or the polygon mirror.

Furthermore, a through hole is formed in the axis of the base 2 along the axis direction, and the light path adjusting device 3 is arranged at the through hole.
Further, the light sources 1 are solid lasers and/or laser diodes. The solid laser can emit visible wavelength, and the laser diode can emit visible wave band after collimation.
Solid-state lasers are lasers in which a solid-state laser material is used as the working substance. The working medium is prepared by uniformly doping a small amount of active ions into crystals or glass serving as a matrix material, and has the characteristics of small volume, convenience in use and high output power. There are three main types of metal ions that can produce stimulated emission in solids: (1) transition metal ion (e.g. Cr)3+) (ii) a (2) Most lanthanide metal ions (e.g. Nd)3+、Sm2+、Dy2+Etc.); (3) actinide metal ions (e.g. U)3+). The main features of these metal ions doped into a solid matrix are: has a wider effective absorption spectral band, higher fluorescence efficiency, longer fluorescence lifetime and narrower fluorescence spectral line, thereby easily generating population inversion and stimulated emission. A commonly used laser crystal is ruby (Cr: Al)2O3Wavelength: 6943A degree, neodymium-doped yttrium aluminum garnet (Nd: Y)3Al5O12For short: YAG, wavelength: 1.064 μm), yttrium lithium fluoride (LiYF4, abbreviation: YLF; YLF, wavelength: 1.047 or 1.053 μm), and the like.
Laser diodes include Single Heterojunction (SH), Double Heterojunction (DH), and Quantum Well (QW) laser diodes. The quantum well laser diode has the advantages of low threshold current and high output power, and is a mainstream product for market application. Compared with a laser, the laser diode has the advantages of high efficiency, small volume and long service life, but the output power is small (generally less than 2mW), the linearity is poor, and the monochromaticity is not good, so that the application of the laser diode in a cable television system is greatly limited, and multi-channel and high-performance analog signals cannot be transmitted. In the return module of the bidirectional optical receiver, a quantum well laser diode is generally used as a light source for uplink transmission.
Example 2:
The coupling device 4 transmits electrical signals by taking light as a medium, and is used for coupling and focusing light with different wavelengths into the light uniformizing device 5 at the same time, and the light uniformizing device 5 can enable output line light sources to be converged into a uniform line.
Further, the coupling device 4 is one or more lenses, i.e. a single aspheric lens or a lens group, and the light homogenizing device 5 is a light homogenizing rod.
The laser in the embodiment can be applied to the field of beauty treatment and can also be applied to other laser application fields requiring light sources with various wavelengths.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included therein.
