Er, Yb: Glass Er, Yb, Cr: Glass
When sourcing an Erbium Glass Laser Rod for your LRF application, there are a few key factors to consider. Unlike the crystal rods, the erbium-doped glass exhibits significant sensitivity to heat or cold, making it challenging to achieve high-level polish accuracy, especially when repeated.
It is a very hygroscopic effecting the coating’s final reliability and long-life endurance.
Arsuf lasers master the erbium rod manufacturing, and we also provide a process of hardening that extends the operation range with minimal thermal lensing.
Standard erbium glass in the market suits applications with repetition rates of 1-6Hz max. However, our material can suit 20Hz and more.
LDT above 10J/CM2 (10Hz 10ns) for glass rods is also a tough challenge, and we our process has proven results of 40-50J and more.
High level of polishing and our hard coating process complete the production cycle. Arsuf Lasers also provides engineering support and failure analysis free if needed. Fill in the contact form and let us know about your needs.
MORE INFORMATION
Er, Cr, Yb phosphate glass
Erbium glass is a type of glass used to generate laser light in the wavelength (1550 nm), which is called “eye safe”. It is made from silica glass that has been doped with the rare earth element erbium.
The erbium ions absorb light at a specific wavelength (1550 nm) and then re-emit it at a higher energy level, which amplifies the signal. Er, Yb: Glass rods are Erbium and ytterbium co-doped phosphate glass that is pumped with 1540 nm laser diodes, while for flash lamp pumped lasers Er, Yb, Cr: Glass is being used.
- The 1st one is the best material for eye-safe and therefore used for any LRF application.
- The 2nd one is used in dermatology systems.
The light output energy is from millijoules to joules level.
Er3+, Yb3+, and Cr3+ doped phosphate glass laser provides a coherent source in the spectral range near 1.5 μm, which is relatively safe for the human eye and is convenient in many applications, such as Lidar and range measurements, and laser surgery.
Frequently Asked Questions
According to the technical specification, a detailed report is supplied to the customer.
No, as all crystals are processed on the same line, the main difference lies in the LIDT requirements (Laser Induced Damage Threshold) determined by the rod's energy density.
Replacement depends on usage, maintenance, and industry, similar to car mileage.
Arsuf is capable of selecting diverse manufacturing and coating processes to maximize crystal quality, efficiency, maximal energy output, above-average lifetime, and high damage threshold. The entire process is performed in-house, leveraging multiple supplier capabilities to ensure the highest customer satisfaction—free from the constraints of a single-supplier approach.
Product warranty is provided by Arsuf, enabling selection from multiple manufacturing and coating technologies for the best outcome.
Erbium Glass Rod Manufacturing – Overcoming Challenges in Laser Rod Production – Video by Arsuf Lasers
Description:
This video provides an in-depth look at the manufacturing challenges and breakthroughs in producing Erbium Glass Rods (Er:rods). These rods, used in diode-pumped and flashlamp-pumped laser systems, are highly sensitive and historically difficult to produce consistently.
Learn how Arsuf Lasers, an ISO 9001-certified global manufacturer, developed a controlled and optimized process through years of experience in defense and industrial laser applications. By redesigning their material treatment, polishing, and coating workflow, they now produce thousands of erbium rods annually with exceptional reliability and minimal rejection rates.
