Formula Used in “Laser Linewidth and Bandwidth Calculator”
The correct assessment of laser performance often requires understanding its linewidth and bandwidth. The standard formula used in our Laser Linewidth and Bandwidth Calculator is derived from fundamental principles of laser physics:
Formula:
$$ Delta nu = frac{1}{tau} $$
Where:
- Δν = Laser linewidth (in Hertz)
- τ = Lifetime of the excited state (in seconds)
Step-by-Step Breakdown of the Formula
Understanding each variable in the formula is vital for accurate calculations:
- Δν (Laser Linewidth): This represents the width of the laser emission spectrum at half its maximum amplitude. It indicates how much the frequency of the emitted light from the laser fluctuates.
- τ (Lifetime of the Excited State): This is the average time an atom stays in the excited state before returning to the ground state. It is a crucial parameter that affects the coherence of the laser output.
Example Calculation
To illustrate how to apply the formula correctly, let’s work through a real-world example to compute the laser linewidth.
| Input Parameter | Value | Unit |
|---|---|---|
| Lifetime of the Excited State (τ) | 5 × 10-9 | seconds |
Using the formula:
$$ Delta nu = frac{1}{tau} = frac{1}{5 times 10^{-9}} $$
Calculating:
$$ Delta nu = 2 times 10^{8} text{ Hz} $$
This calculation shows that the laser linewidth is 200 MHz, indicating a certain level of frequency stability in the laser output. For practical applications, such stability is essential in telecommunications and precision measurement systems.
