Description
Technical field
This utility model relates to pulse laser, especially relates to a kind of dress realizing the output of pulse laser power stability
Put.
Background technology
Existing pulse laser typically uses directly output, and its shortcoming is that undulatory property is bigger, is unfavorable for much applying.
Summary of the invention
The purpose of this utility model is to provide the laser that can realize laser instrument stably to export, and reduces mean power undulatory property
A kind of realize pulse laser power stability output device.
This utility model is provided with light splitting eyeglass, acousto-optic modulator, probe, comparison circuit, driver；Described light splitting eyeglass sets
On the laser beam of laser instrument output, acousto-optic modulator be located at light splitting eyeglass through on light beam, probe is located at light splitting eyeglass
Reflected light path on, the electrical signal of probe connects the input of comparison circuit, outside another input of comparison circuit is external
Portion's input signal, the input that the cut-off signals outfan of comparison circuit is driver connected, the output termination acousto-optic modulation of driver
The input of device, acousto-optic modulator output laser pulse signal.
This utility model installs a power stability device in the output light path of pulse laser additional, it is achieved swashing of laser instrument
Light stably exports, and reduces mean power undulatory property.
Accompanying drawing explanation
Fig. 1 is the structure composition schematic diagram of existing laser instrument.
Fig. 2 is the structure composition schematic diagram of this utility model embodiment.
Detailed description of the invention
Fig. 1 provides the structure composition schematic diagram of existing laser instrument, and in FIG, the laser beam 9 of laser instrument 1 output leads to
Cross any optical element 7 to export.This way of output laser directly exports, and undulatory property is bigger.
Fig. 2 provides the structure composition schematic diagram of this utility model embodiment, and this utility model embodiment is provided with light splitting eyeglass
2, acousto-optic modulator 3, probe 4, comparison circuit 5, driver 8；Described light splitting eyeglass 2 is located at the laser beam 9 of laser instrument 1 output
On, acousto-optic modulator 3 be located at light splitting eyeglass 2 through on light beam, probe 4 is located on the reflected light path of light splitting eyeglass 2, pops one's head in 4
Electrical signal connect the input of comparison circuit 5, the external external input signal of another input 6 of comparison circuit 5, compare
The input of the cut-off signals outfan driver connected 8 of circuit 5, the input of the output termination acousto-optic modulator 3 of driver 8,
Acousto-optic modulator 3 output laser pulse signal.
The laser beam 9 of laser instrument 1 output placed the light splitting eyeglass 2 of a half-reflection and half-transmission, for from laser light
Bundle 9 separates a part of light and enters high-sensitivity probe 4；Probe 4 in real time detection power levels and be converted into the signal of telecommunication export than
Relatively circuit 5.The output of pulse laser is usually pulse output, and frequency is usually several hertz to tens KHz.Work as CO2Output
During one pulse, high-sensitivity probe captures this pulse and is converted into the signal of telecommunication and exports comparison circuit 5, with external input signal
6 compare, and the signal once fed back or the integration of feedback signal exceed input signal, then comparison circuit 5 exports a cut-off signals
To driver 8, driver 8 drives acousto-optic modulator 3 to work, and makes the laser through acousto-optic modulator deviate original output side
To, until the output of this laser pulse is complete, and then realize turning off the purpose of laser output.Realize steady by the pulse that suppression is too high
Determine the purpose of Output of laser.
This utility model addition of light splitting eyeglass 2 and acousto-optic modulator 3 in original laser optical path output；Light splitting eyeglass
A part of las er-guidance enters high-sensitivity probe, and probe converts optical signal into the signal of telecommunication and is input to comparison circuit 4, with outside
Input signal 6 exports cut-off signals more afterwards and drives acousto-optic modulator to turn off to driver 8, the driving signal of driver 8 output
Laser exports.
Placed light splitting eyeglass harmony photomodulator on the output light path of laser can be to put together compactly, also simultaneously
Can be spaced distant, but all in the light path of laser output；
The signal fed back by comparing external input signal 6 and high-sensitivity probe judges whether to turn off laser, and this two-way is believed
Number before comparison may be through certain process；
External input signal 6 can be input in real time, it is also possible to be to be stored in advance in comparison circuit 5.
