Abstract

The invention discloses an underwater laser transmitter capable of generating various laser patterns. The underwater laser transmitter comprises a laser driving circuit, a laser and a laser pattern selection unit. The laser driving circuit comprises an MCU, an APC bias driving circuit, a switch module and a current adjusting unit, and is used for protecting a laser from being damaged by high current under the condition that stable output power is maintained. The laser comprises a laser working substance, an excitation pumping system and an optical resonant cavity. The laser pattern selection unit comprises a rotating wheel and a control circuit and is used for realizing selection of laser patterns of the laser. The underwater laser capable of generating various laser patterns in the blue-green wave band is simple in structure, low in cost, long in service life, high in pulse energy, stable in wavelength, narrow in spectrum, small in size and suitable for a seawater spectrum transmission window.

Description

technical field [0001] The invention relates to the technical field of laser design, in particular to an underwater laser emitter capable of generating multiple laser patterns. Background technique [0002] Lasers, also known as laser diodes, use media such as solids (crystals, glasses), gases (atomic gases, ionic gases, molecular gases), semiconductors, and liquids as working materials for lasers. They are small in size and long in life, and can use simple The method of injecting current acts as an excitation pumping system (also known as pumping). At the same time, its operating voltage and operating current are compatible with integrated circuits, and can be monolithically integrated with integrated circuits. With the characteristics of high electro-optic conversion efficiency, it is widely used in laser welding, material heat treatment, additive manufacturing, communication, sensing and other fields. [0003] However, the following problems still exist in the field of ...
