+# <p align="center">Laser Linewidth And Bandwidth Calculator</p>
+
+## Description :-
+
+A simple web-based calculator to compute the **linewidth** and **bandwidth** of a laser. These parameters are critical in determining the performance and applications of a laser system, such as in fiber optics.
+
+## Tech Stacks :-
+
+- HTML
+- CSS
+- JavaScript
+
+## Features :-
+
+- Accepts **Frequency (Hz)** and **Quality Factor (Q)** as inputs.
+- Calculates:
+  - **Linewidth** = Frequency / Quality Factor
+  - **Bandwidth** = GainBandwidth × (1 - DampingFactor)
+- Provides real-time results with an interactive UI.
+
+## Screenshots :-
