Description
Technical field
The present invention relates to active light emissive device, be specifically related to the semiconductor laser group of a kind of series connection.
Background technology
Being provided with semiconductor laser chip in semiconductor laser, the operation principle of semiconductor laser chip is logical
Cross certain energisation mode, between the carrying of semiconductor substance, or the carrying and impurity of semiconductor substance
Between energy level, it is achieved the population inversion of nonequilibrium carrier, when a large amount of electricity being in population inversion state
When son and hole-recombination, just produce stimulated emission effect.
During semiconductor laser work, amount of heat can be produced, the most high-power semiconductor laser,
In order to make heat radiation is good, some technique can increase the external surface area of semiconductor laser, i.e. increases heat radiation
Face, but to be allowed to again volume excessive for this scheme, when multiple semiconductor laser cooperation, above two
Individual problem just seems more crucial.
Summary of the invention
For the deficiencies in the prior art, the invention discloses the semiconductor laser group of a kind of series connection.
Technical scheme is as follows:
The semiconductor laser group of a kind of series connection, including multiple semiconductor lasers；Each semiconductor laser
Including include in quasiconductor mounting seat and quasiconductor mounting seat in isosceles triangle be placed with upper electrode, left electrode,

Fix on pin 9 with second.
It is connected by busbar between multiple semiconductor lasers；Semiconductor laser fixing at end
Connecting on pin and have contact electrode, connecting on contact electrode has wire
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above example.Permissible
Understanding, those skilled in the art the most directly derive or associate
The oher improvements and changes arrived, within being all considered as being included in protection scope of the present invention.
