Calculation between cavity spectrum and frequency distance
Caculates the cavity spectrum and the frequency distance between TEM_00 and higher order modes m+n. Two curved mirrors possible. Programm made by T. Legero.
Parameter
- Radius of curvature of mirror R1: R1= 1 m
- Radius of curvature of mirror R2: R2= 1 m
- Cavity Length: L= 0.48 m
- Reflectivity of mirrors: R= 0.99998
- Speed of light: c= 299792458 m/s
Step 1: Calculate the Free-Spectral-Rang and Gouy-Phase
- Free-Spectral-Rang: FSR
- Gouy-Phase: Gouy
$$FSR = \frac{c}{2\cdot L}$$ $$Gouy = \frac{FSR}{\pi} \cdot \arccos \left( \sqrt{(1-\frac{L}{R1})\cdot(1-\frac{L}{R2}} \right)$$
⇒
- FSR = 312.284 MHz
- Gouy = 101.783 MHz
