The invention is applicable to the electronic tool field and provides a pulse laser seed source light detection tool. The pulse laser seed source light detection tool comprises a test lead, a power supply wire and a circuit board; the circuit board is successively connected to an AC / DC conversion module, a DC voltage reduction circuit and a signal amplification circuit; the AC / DC conversion module is connected to external city power through the power supply wire to convert 220V AC y to 24V DC ; the DC voltage reduction circuit reduces the 24V DC voltage to 12V -5V DC voltage to provide working voltage to the signal amplification circuit; one end of the test lead is connected to a pulse laser seed source light monitoring point and the other end is connected to the input end of the signal amplification circuit; and the signal amplification circuit amplifies the electric signal converted by the monitoring point light signal. The pulse laser device seed source light monitoring point is connected through a test lead, the monitoring point can be chosen and moved according to the needs, and amplification can be performed on the electric signal converted from the monitoring point light signal. The invention can determine whether the light in seed source is transmitted into the amplifier, and is stable in test and high in uniformity.

Description

technical field [0001] The invention belongs to the field of electronic tooling, in particular to a pulse laser seed source light detection tooling. Background technique [0002] The final output light of the pulsed laser is obtained by amplifying the light from the seed source through an amplifier doped with ytterbium fiber. If there is no light input from the seed source into the amplifier for a period of time, it is easy to damage the amplifier Yb-doped fiber. Therefore, it is necessary to add a protection function of seed source light monitoring: when the light of the seed source is not detected within a certain period of time, the working voltage of the seed source and the amplifier pump will be disconnected. The premise of the implementation of the protection function is to set the monitoring point of the seed source monitoring inside the laser in advance when the optical module is manufactured. The previous production process used a multimeter to measure the voltage ...
