+# Laser Linewidth and Bandwidth Calculator
+
+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.
+
+---
+
+## Features
+- Accepts **Frequency (Hz)** and **Quality Factor (Q)** as inputs.
+- Calculates:
+  - **Linewidth** = Frequency / Quality Factor
+  - **Bandwidth** = Linewidth (assumed equal in this context).
+- Provides real-time results with an interactive UI.
+
+---
+
+## Technologies Used
+- **HTML**
+- **CSS**
+- **JavaScript**
+
+---
+
+## Setup Instructions
+
+1. Clone or download this repository to your local machine.
+2. Run the index.html file.
+
