Introduction and Operation procedure:

Many diodes have a strippable fiber that each time after you use it, you must remove of the insulation ( strip the fiber), as well as cut it clean and sharp (cleave the fiber). This strippable fiber is economical, and available in 200 micron (endo) and 400 micron (surgical diode dentistry) sizes for all CHEESE lasers from GIGAA LASER.

However the question is how to initiate those strippable fibers?

The process of initiating the tip will concentrate the laser energy in the tip essentially making it a “hot tip”. The monochromatic laser light is turned into heat and hence this process is called a photothermal reaction. The process of ablation or vaporization requires the tip of the diode laser to be initiated.

The process of initiation traps almost all of the energy in a very small zone ( likely 20-40 micron layer) and the tip can heat up to 1500 Celsius in just a few couple of seconds. Care must be taken with these temperatures to not “melt” the tip, so lower energies will yield better ablation of the tissue if proper initiation of tip is accomplished. Starting with a setting of 0.8-1.0 continuous wave after initiation of the tip is a nice starting point for many procedures to minimize the collateral thermal damage that can occur.

The initiation material will be better as articulating paper

Procedure
1. Select the fiber you need,200um or 400um bare fiber
2. Set the laser to CW 1.0W
3. Touch the tip to the articulating paper first then step on foot pedal for ONE second.
4. Repeat 8 times or more.
5. Touch initiated tip to tissue holding tip stationary and look for signs of ablation
6. Begin procedure or reinitiate tip if needed on the articulating paper.

Increase the power when you do not get initiation tip.
