Abstract

The invention discloses a holographic laser transmitter and a manufacturing method thereof. The holographic laser transmitter comprises: a laser transmitting module which comprises a first substrate and a light-emitting functional film layer disposed on the first substrate; and a volume holographic grating module arranged in the light-transmitting area, far away from one side of the first substrate, of the light-emitting functional film layer. The holographic laser transmitter can emit high-power laser with a smaller angle, a specific polarization mode and a specific wavelength.

Description

technical field

[0001] The present application generally relates to the technical field of laser imaging, and in particular relates to a holographic laser emitter and a manufacturing method thereof. Background technique

[0002] A laser is a device that uses the principle of stimulated radiation to amplify or oscillate light in certain excited substances to emit laser light (laser).

[0003] Vertical-cavity surface-emitting laser (Vertical-Cavity Surface-Emitting Laser, VCSEL) is a new type of laser, which has the characteristics of high power, single longitudinal mode, long life, circular spot output and easy integration. Sensing and other fields have a wide range of applications.

[0004] However, as the requirements for the laser emission power of VCSEL are getting higher and higher, the angle of light emitted by the laser is larger, and the difficulty of laser mode selection and polarization modulation is increasing, which restricts the application of VCSEL in many impo...
