The invention discloses a high-power water-cooled semiconductor laser, which comprises a water-cooled substrate provided with a water-cooled flow channel. At least two single lasers are mounted on the water-cooled substrate, and electrode copper sheets are led out downwardly from two sides of each single laser and are electrically connected with a circuit board mounted at the bottom of the water-cooled substrate to serially connect all the single lasers together. The high-power water-cooled semiconductor laser is simple in structure and low in cost; and all the single lasers are connected through the circuit board, and the circuit board and the electrode copper sheets are pressed by fixing screws, so that maintenance and replacement are facilitated only by replacing one single laser in failure, waste is avoided to some degree, and the high-power water-cooled semiconductor laser is high in flexibility and replaceability during manufacture and use.
Description
technical field [0001] The invention relates to a semiconductor laser, in particular to a high-power water-cooled semiconductor laser. Background technique [0002] Semiconductor lasers are the most important class of lasers in practice. It is small in size, long in life, and can be pumped by a simple way of injecting current. Its operating voltage and current are compatible with integrated circuits, so it can be monolithically integrated with it. And it can also directly modulate the current with a frequency up to GHz to obtain high-speed modulated laser output. Due to these advantages, semiconductor diode lasers have been widely used in laser communication, optical storage, optical gyro, laser printing, ranging and radar. [0003] At present, high-power semiconductor lasers are being pursued by various countries due to their broad application prospects and huge potential markets. The current high-power semiconductor lasers on the market basically integrate multi-watt las...
