Welcome to the Fiber Size Calculator where you can quickly find out what minimum fiber size you need or the maximum power amount for your needs. Click on either CW or Pulsed to get started.

Minimum Fiber Size or Laser Power?

Fiber Size

Laser Power

Select Fiber Size to calculate the minimum fiber size that can be used with a given laser source.

Select Laser Power to calculate the maximum power that can be put into the selected fiber core diameter.

What is the Pulse Duration?

Pulse Duration (τ):

Pulsed lasers with a pulse duration greater than 1 microsecond are treated as CW lasers in all calculations.

Ok, we need some numbers:

Wavelength (λ) nm

Fill Ratio %

Enter the values above. Fiber Core Size is the minimum core size required for the power level you have selected. Standard sizing may not be available in the exact diameter calculated, so please round up to the nearest standard size. Wavelength is the measure of peak to peak in nm. Fill Ratio is the percentage filled.

Laser Power

Select Fiber Size to calculate the minimum fiber size that can be used with a given laser source.

Select Laser Power to calculate the maximum power that can be put into the selected fiber core diameter.

Average Power or Peak Power?

Average Power

Peak Power

Review your laser specs and enter values in terms of average power.

Alternatively, calculations can be made in terms of peak power.
