Co: Spinel
Arsuf lasers’ reliable product
When coming to sourcing a Co:Spinel (Cobalt-doped Magnesium Aluminate) Passive Q-Switch for your eye-safe 1.54um Glass (Er) laser rod there are a few parameters to consider, first, is the optical quality derived from uniform Co distribution and high absorption crystal then good polish complying with the transmission value that is a function of the switch thickness and the last one hi LDT hard coating that can cope with high power density in the laser cavity.
Arsuf lasers’ spinel crystal is a top-level crystal. A high level of polishing and our hard coating process complete the production cycle.
Arsuf lasers also provide engineering support and failure analysis, free if needed.

MORE INFORMATION
Co: Spinel (Co2+:MgAl2O4) Crystal (known also as Co: MALO)
Co2+MgAlO4, also known as spinel doped with Cobalt, is an ideal mineral, passive Q-switch, for lasers emitting at 1.2~1.6 μm, in particular, for eye-safe 1.54 μm Er: glass lasers. A Q-switch, also known as a mode-locked laser, is a device that is used to create very short, intense pulses of light.
Spinel is used as a Q-switch because it has a large electro-optic coefficient and can change its refractive index quickly in response to an electric field.
This makes it well-suited for use in laser systems that require very short pulses of high-energy light.
The excellent optical, mechanical, and thermal properties of the crystal give an opportunity to design compact and reliable laser sources with this passive Q-switch.
It is widely used in eye-safe Er: Glass lasers (1.54µm) as showing low optical losses.
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.
