At Arsuf Lasers Ltd, we specialize in the design, manufacturing, and qualification of erbium-doped glass (Er:Glass) laser rods for demanding medical, industrial, defense, and research laser systems.
The following video provides a direct look into our manufacturing philosophy, proprietary processes, and the engineering challenges involved in producing high-energy, eye-safe laser gain media at the highest international standards.

Why Erbium-Doped Glass Laser Rods?

Erbium-doped glass rods are a preferred laser gain medium for high-energy pulsed systems operating around 1.54 µm, an eye-safe wavelength widely used in:

• Laser range finding (LRF)
• LIDAR and sensing
• Medical laser systems
• Defense and aerospace laser platforms
  
  

Unlike crystalline gain media (such as Nd:YAG or Er:YAG), glass-based laser rods enable:

• Higher pulse energy at lower repetition rates
• Larger aperture designs
• Improved energy storage characteristics

However, these advantages come with significant manufacturing challenges.

Manufacturing Challenges: Glass vs. Crystal Laser Rods

Erbium-doped phosphate and silicate glasses are thermally and chemically sensitive materials. During production, they are highly susceptible to:

• Thermal stress and micro-cracking
• Surface contamination
• Sub-surface damage during grinding and polishing
• Coating adhesion and laser-induced damage (LIDT limitations)
  
  

Traditional fabrication methods often degrade coating durability, leading to premature optical failure in high-energy laser systems.

Arsuf Lasers’ Advanced Manufacturing Approach

In the video, we demonstrate how Arsuf Lasers overcame these challenges by combining:

• Advanced German optical fabrication machinery
• Proprietary polishing sequences optimized for sensitive glass hosts
• Non-traditional processing flows that maximize coating strength
• Strict environmental control during polishing and coating
• In-house metrology and laser damage threshold validation
  
  

By re-engineering the sequence of polishing, coating, and coring, we achieved exceptional coating durability capable of surviving millions of laser shots, even in compact, small-diameter rods.

Precision, Uniformity, and Doping Control

Producing reliable Er:Glass laser rods requires extreme control of dopant distribution. Arsuf Lasers applies deep expertise in handling delicate rare-earth and transition-metal dopants such as:

• Erbium (Er³⁺)
• Ytterbium (Yb³⁺)
• Chromium (Cr³⁺)
  
  

This ensures:

• Excellent optical homogeneity
• Stable laser performance
• Repeatability across production batches
• Compliance with military and industrial qualification standards
