Description
Technical field
The present invention relates to a kind of femto-second laser, be specifically related to the fine temperature control tank of the split type dish of a kind of femto-second laser.
Background technology
The coiling, distortion, temperature, vibration etc. of the optical fiber of non-linear rotatory polarization modelocked fiber femto-second laser inside all can have a huge impact its output stability, and therefore optical fiber needs coiling neat, distortionless, and Stability Analysis of Structures after dish is good, temperature controls to get well.Existing femto-second laser dish fibre is all as a whole with housing, and housing surrounding dish is fine, as shown in Figure 1, and adds temperature control or does not add temperature control, fine and do not control fiber optic temperature unit at inner disk.
The fine groove of non-linear rotatory polarization modelocked fiber femto-second laser dish and whole housing as a whole, impact by temperature is very large, equalized temperature to be realized for a long time after start, run the variations in temperature that can affect again optical fiber after a period of time after various device heating, be difficult to realize the long-time running of laser and stable.And housing surrounding dish is fine, and optical fiber free distance is long, the impact to be easily given a shock etc., and easily produce fiber-optic twist when dish is fine, thus femtosecond is exported have an impact.
Simultaneously as the fine groove of fruit tray and whole housing as a whole, then to ensure fiber lengths and coil towpath electrical path length and conform to, otherwise fiber reel good after just can not arrive precalculated position, therefore this just creates restriction to the design of fiber lengths.
Summary of the invention
The object of the invention is, for the fine groove Problems existing of existing integral type dish, to provide the split type dish of a kind of femto-second laser fine temperature control tank, make fiber reel around neatly, distortionless, Stability Analysis of Structures after dish is good, temperature is controlled well.
Technical solution of the present invention is: the fine temperature control tank of the split type dish of a kind of femto-second laser, coil between fine groove and laser housing and support with heat insulation post, coiling fine groove is fixed on laser housing by fixing hole, coil to clip between fine groove and laser housing and coil fine groove embedded temperature sensors, temperature sensor is placed in below the fine groove of dish.
Further, the fine groove of described dish is that 8 letter disks that two circles are connected are fine.
Further, described femto-second laser optical device putting position is femtosecond laser resonant cavity optical element placement area, and optical component is all fixed on laser housing, isolates with the fine groove of dish.
Further, between the fine groove of described dish and laser housing, TC cooling piece is set.
Fine for dish groove and laser housing are separated into two structures by the present invention, coil and to support with heat insulation post between fine channel mould block and housing thus to make both isolate, avoid the impact of case temperature on fiber section.TEC is clipped with between the fine groove of hour indicator and housing, coil fine groove embedded temperature sensors, controlled by external circuit so again, the temperature control to the fine groove of dish can be realized, and coil fine groove and housing isolation design us can be made the action of coiling fine groove and do independent temperature control, just can ensure the temperature stability of fiber section thus, solving temperature affects problem to femtosecond laser.
Add 8 unique letter disk method for fiber, better make fiber reel in the fine trough floor of dish, solve because fiber lengths and dish towpath electrical path length are not inconsistent and the problems such as the little coil radius caused, larger distortion, and shorten the free distance of optical fiber, can better fixed fiber, ensure that stable, the temperature of optical fiber, more can ensure the stability that femtosecond exports.
Beneficial effect of the present invention is as follows:
(1) the present invention is the design of 8-shaped dish fibre, can utilize the inner space of laser housing greatly.
(2) the present invention is the fine groove of split dish, and can put into enclosure interior again at the outer good optical fiber of face of laser housing, fine difficulty is coiled in reducing of large degree.And fiber reel can be made around more clean and tidy firm, avoid the distortion of optical fiber, substantially increase the stability of femto-second laser.
(3) isolate between the fine groove of mid-game of the present invention and laser housing, avoid the impact of case temperature on fiber section.
(4) the present invention has the design of TEC temperature control, coil fine groove and housing is isolated, temperature sensor is placed in below the fine groove of dish, be used for detection optical fiber groove temperature, controlled by external circuit, such design can make us do the action of independent temperature control to the fine groove of dish, temperature control better effects if again, like this can well real-time ensuring fiber optic temperature not by external influence, thus femto-second laser still can be able to be used under comparatively adverse circumstances.
(5) if need speed faster to reach stabilized operating temperature, then two or more TEC can be used to carry out temperature control simultaneously.
(6) dish method for fiber of the present invention is that 8 letter disks are fine, no matter enter optical fiber over there finally can be fine at the light-emitting directions wanted, can solve putting of optical fiber fusion welding point position, fiber lengths is not inconsistent with dish towpath footpath, and the dish of optical fiber different directions such as to walk at the problem.

Embodiment
Below in conjunction with accompanying drawing, the present invention is described further.
As shown in Figure 2 and Figure 3, the fine temperature control tank of a kind of split type dish of femto-second laser, coil between fine groove 1 and laser housing 2 and support with heat insulation post 4, coiling fine groove 1 is fixed on laser housing 2 by fixing hole 3, coil to clip between fine groove 1 and laser housing 2 and coil fine groove embedded temperature sensors 5, temperature sensor 5 is placed in below the fine groove 1 of dish.
The fine groove 1 of described dish is that 8 letter disks that two circles are connected are fine.
Femto-second laser optical device putting position is femtosecond laser resonant cavity optical element placement area, and optical component is all fixed on laser housing 2, isolates with the fine groove 1 of dish.
Between the fine groove 1 of described dish and laser housing 2, TC cooling piece 6 is set.
The invention enables dish fibre more clean and tidy firm, avoid the distortion to optical fiber when coiling fine, make product not be subject to the impact of the factors such as extraneous vibration.
The design of optical fiber TEC temperature control, makes optical fiber not be subject to the impact of ambient temperature, ensure that the stability of product simultaneously.And coil fine groove and housing isolation design us can be made the action of coiling fine groove and do independent temperature control, temperature control better effects if.
