Optic fibre cooler pan and fiber laser and optical fiber amplifier

The utility model provides an optic fibre cooler pan and fiber laser and optical fiber amplifier. The one side of optic fibre cooler pan is provided with the runway, the runway is used for making optic fibre to follow the runway coils on the optic fibre cooler pan, just the arrangement structure of runway makes optic fibre coil on the optic fibre cooler pan according to the specific structure of coiling. Arrangement structure through with runway in the optic fibre cooler pan improves, when the fiber reel around in in the time of on the optic fibre cooler pan, the second of optic fibre end canwind from the inner circle of a plurality of optic fibre circle for outside the optic fibre both ends all are located a plurality of optic fibre circles, unnecessary upwards perk when other componentsand parts are connected at the optic fibre both ends, and then solved the optic fibre that the tradition method of coiling must lead to and fly fine problem. Based on above -mentioned optic fibre cooler pan, the utility model
