## 🌟 Overview

The WIA-DEF-007 standard defines the technical framework for directed energy laser weapon systems, including laser physics, beam control, thermal management, targeting systems, and atmospheric propagation modeling. This standard focuses primarily on defensive applications such as Counter-Rocket, Artillery, and Mortar (C-RAM) systems.

**홍익인간 (弘益人間) - Benefit All Humanity** - This standard aims to provide a scientifically-grounded foundation for defensive laser systems that protect civilians and infrastructure while promoting peace and security through technological advancement.

## 🎯 Key Features

- **Directed Energy Physics**: Mathematical framework for high-energy laser propagation
- **Laser Types**: Support for Chemical, Solid-State, Fiber, and Free Electron lasers
- **Beam Control**: Advanced beam steering, focusing, and adaptive optics
- **Thermal Management**: Heat dissipation and thermal blooming compensation
- **Atmospheric Propagation**: Modeling of atmospheric effects on beam quality
- **Targeting Systems**: Precision tracking and engagement algorithms
- **Safety Protocols**: Multi-layer safety systems and operational constraints
- **C-RAM Applications**: Specialized configurations for defensive counter-measures

## 📊 Core Concepts

### 1. Laser Power Density

```
I = P / (π × r²)
```

Where:
- `I` = Intensity (W/m²)
- `P` = Laser power (W)
- `r` = Beam radius at target (m)

### 2. Thermal Blooming Effect

```
Δθ = (k × P × L) / (ρ × Cp × v × r⁴)
```

Where:
- `Δθ` = Beam deflection angle
- `k` = Absorption coefficient
- `P` = Laser power
- `L` = Propagation distance
- `ρ` = Air density
- `Cp` = Specific heat capacity
- `v` = Wind velocity
- `r` = Beam radius

### 3. Beam Quality (M² Factor)

```
M² = (π × w₀ × θ) / λ
```

Where:
- `M²` = Beam quality factor (1.0 = perfect Gaussian beam)
- `w₀` = Beam waist radius
- `θ` = Far-field divergence half-angle
- `λ` = Wavelength

### 4. Atmospheric Transmission

```
T = exp(-α × L)
```

Where:
- `T` = Transmission coefficient
- `α` = Atmospheric attenuation coefficient
- `L` = Propagation distance

## 🔧 Components

### TypeScript SDK

```typescript
import {
  calculateBeamIntensity,
  validateEngagement,
  createLaserSystem,
  simulateAtmosphericPropagation
} from '@wia/def-007';

// Create a laser weapon system
const system = createLaserSystem({
  type: 'solid-state',
  power: 100000, // 100 kW
  wavelength: 1.064e-6, // 1064 nm
  beamQuality: 1.5,
  coolingCapacity: 150000 // 150 kW
});

// Calculate beam intensity at target
const intensity = calculateBeamIntensity({
  power: 100000,
  beamRadius: 0.05, // 5 cm at target
  range: 2000 // 2 km
});

// Validate engagement
const validation = validateEngagement({
  target: {
    type: 'mortar-shell',
    range: 2000,
    velocity: 300,
    size: 0.1
  },
  weather: {
    temperature: 20,
    humidity: 60,
    visibility: 10000
  }
});

console.log(validation.isValid, validation.estimatedTimeToKill);
```
