Description
Technical field
The utility model is related to a kind of power monitor device of high power semiconductor pump source ageing system, particularly for light
In the ageing system of fine coupling semiconductor laser device.
Background technology
It is to use inner chamber to be spherical integrating sphere that laser receiver is used in traditional pumping source ageing process.Integrating sphere type
Power monitor device it is relatively accurate to power test, cost is very high.But be applied in the ageing system of laser, laser
Reception device only needs to absorb laser and judges whether laser exports to judge that laser has fault-free, cost in ageing process
Control needs to consider.
The content of the invention
The utility model carries to realize power monitoring of the semiconductor pumping sources in ageing process and reduction equipment cost
For a kind of power monitor device of high power semiconductor pump source ageing system.The device can be good at realizing pumping source old
Power monitoring protection in change system, while production cost is very low.
What the utility model was achieved through the following technical solutions：
A kind of power monitor device for high power semiconductor pump source ageing system, including laser pick-off cavity, light
Electric diode, optical fiber hold-down bars, it is characterised in that：Described laser pick-off cavity is closed, and laser pick-off inside cavity is set
There is reflecting slant, the optical fiber of semiconductor pumping sources is fixed on optical fiber hold-down bars, optical fiber hold-down bars insertion laser pick-off cavity
In cavity lid, photodiode is arranged on laser pick-off cavity.
Described laser pick-off cavity is closed aluminum enclosure.
Laser light incident is to after laser pick-off inside cavity, and the reflection by the reflecting slant of laser pick-off cavity causes laser
Absorbed by laser pick-off cavity, while measuring laser pick-off chamber by the power monitoring photodiode on laser pick-off cavity
Internal portion laser intensity, plays a part of protecting semiconductor pumping sources by the electric-control system of laser.
Laser pick-off inside cavity reflecting slant of the present utility model, which is designed, causes laser largely to reflex to cavity bottom,
Heat is quickly exported after being absorbed by cavity, device caloric value very little itself；Due to passing through photodiode exploring laser light energy
Amount change becomes to play the energy variation of the purpose and monitoring semiconductor pumping sources of protection semiconductor pumping sources in ageing process
Gesture.
The utility model is by laser light incident to closed laser pick-off cavity, and one is reflected divergencing laser using reflecting slant
Reflecting slant is set inside aluminum enclosure, forward direction input laser reflected, laser heat is absorbed by laser pick-off cavity；Two
It is to utilize photodiode exploring laser light receiving cavity inner laser, laser power is judged by system, protection laser is reached
Purpose.
