Abstract

The invention discloses a laser diode with a power supply. The laser diode comprises a base, wherein the base is provided with an outer shell, a laser source and an actuator are arranged in the outershell, the laser source is connected with a temperature controller monitoring temperature of the laser source, the actuator is provided with a convex mirror, the convex mirror is arranged directly above the laser source, a transparent window is arranged on the upper part of the outer shell, a pin A and a pin B are arranged on the base, the laser source is provided with a laser crystal, a driver ICis arranged beside the actuator, and the driver IC converts a constant voltage input from the pins into a constant operating current of a laser tube. The laser diode disclosed by the invention is provided with its own power supply and is packaged with the power supply, thereby greatly optimizing the structure, reducing the cost, and improving the production efficiency.

Description

technical field [0001] The invention belongs to the field of optical technology, and in particular relates to a laser diode with its own power supply. Background technique [0002] There is only one laser chip on the bracket cup of an ordinary laser diode, and the drive circuit in the external circuit needs to be used to provide a constant current for it to prevent the laser tube from failing too quickly. Such a structure not only increases the cost, but also increases the production process and cost. The external driver needs to have an additional driver part, the circuit is slightly complicated, and there is also a problem of occupying board space. Contents of the invention [0003] The purpose of the present invention is to provide a laser diode with its own power supply. The power supply is directly put into the laser diode, that is, the laser diode has its own power supply and is packaged, which greatly optimizes the structure, reduces the cost, and improves the produ...
