Abstract

The present invention relates to a sheath beam stripper (1) which discharges pumping light that cannot be absorbed by active fiber in high-power fiber laser systems, from fiber optic cable; and production method (100) thereof

Claims

1. Production method (100) of a sheath beam stripper (1) which is used as a beam stripper characterized by comprising steps of: inserting the thermoplastic polymer (A) in film form onto the aluminium frame (B) (101); putting the aluminium frame (B) whereon the thermoplastic polymer film (A) is located, into a tube (E) that is heated by the thermal oven (C) and connected to the vacuum pump (D) (102); inserting the fiber optic cable (Y), outer surface of which will be coated, into the thermal oven (C) (103); switching the thermoplastic polymer film (A) into a vapour phase by keeping it at a certain temperature inside the thermal oven (C) (104); intensifying the thermoplastic polymer (A) that is switched into a vapour phase inside the oven (C) and resistant to high temperatures, by reducing the temperature inside the oven (C) (105); and obtaining the sheath beam strippers (1) by coating the thermoplastic polymer (A), which is intensified in the form of water droplets in nano or micro sizes, onto the fiber optic cable (Y) (106).

2. Production method (100) of a sheath beam stripper (1) according to claim 1; characterized in that the thermoplastic polymer (A) used is polyether sulfone (PES).

3. Production method (100) of a sheath beam stripper (1) according to claim 1; characterized in that the thermoplastic polymer film (A) is provided in a temperature range of 290-310° C. inside the thermal oven (C) and it is switched to a vapour phase after being kept for 25-35 minutes.

4. A sheath beam stripper (1) which is obtained by a method according to claim 1 and formed by virtue of the fact that the polymer holds on to the surface in islets (Z) like water drops on hydrophobic surfaces and then covers an area without contacting each other and ensures that the light scatters better than thin films by means of this configuration.

5. A sheath beam stripper (1) which is obtained by a method according to claim 1, aims to protect fiber against external effects externally, to increase its resistance to high temperature, and to strip the light that has a new area of usage.

[0017] Production method (100) of a sheath beam stripper (1) which is used as the inventive beam stripper comprises steps of: [0018] inserting the thermoplastic polymer (A) in film form onto the aluminium frame (B) (101); [0019] putting the aluminium frame (B) whereon the thermoplastic polymer film (A) is located, into a tube (E) that is heated by the thermal oven (C) and connected to the vacuum pump (D)(102); [0020] inserting the fiber optic cable (Y), outer surface of which will be coated, into the thermal oven (C) (103); [0021] switching the thermoplastic polymer film (A) into a vapour phase by keeping it at a certain temperature inside the thermal oven (C)(104); [0022] intensifying the thermoplastic polymer (A) that is switched into a vapour phase inside the oven (C) and resistant to high temperatures, by reducing the temperature inside the oven (C) (105); and [0023] obtaining the sheath beam strippers (1) by coating the thermoplastic polymer (A), which is intensified in the form of water droplets in nano or micro sizes, onto the fiber optic cable (Y)(106).

[0024] In the inventive method (100), the thermoplastic polymer (A) which is used at the step of inserting the thermoplastic polymer (A) in film form onto the aluminium frame (B) (101) is preferably polyether sulfone (PES).

[0025] In the inventive method (100), at the step of switching the thermoplastic polymer film (A) into a vapour phase by keeping it at a certain temperature inside the thermal oven (C) (104), a temperature range of 290-310° C. is provided inside the thermal oven (C) and transition to a vapour phase occurs after waiting for 25-35 minutes.

[0026] The sheath beam stripper (1) obtained by the inventive method (100) is formed by virtue of the fact that the polymer holds on to the surface in islets (Z) like water drops on hydrophobic surfaces and covers an area without contacting each other and the light scatters better than thin films by means of this configuration.

[0027] The sheath beam stripper (1) obtained by the inventive method (100) aims to protect fiber against external effects externally, to increase its resistance to high temperature, and to strip the light that has a new area of usage.

[0028] Within these basic concepts; it is possible to develop various embodiments of the inventive sheath beam stripper (1) and production method thereof (100); the invention cannot be limited to examples disclosed herein and it is essentially according to claims.
