Yb:YAG Dual Band DBHR Mirrors

Yb:YAG Dual-Band DBHR Mirrors: purpose, main function, customization (GDD, LIDT, Reflection, etc.), production and alternatives

What is function and porpose Yb:YAG Dual-Band Mirrors?

Main function of Yb:YAG Dual-Band Mirror is to effectively reflect two Yb:YAG laser wavelengths (fundamental wavelength 1030 nm and/or it’s harmonics, such as 515 nm, 343 nm, etc.). These mirrors reflect both wavelengths at the designed angle of incidence allowing efficient beam control within optical system. This feature allows single DBHR mirror to replace two Yb:YAG Laser Line (HR) mirrors

Custom Yb:YAG DBHR Mirrors

Alien Photonics DBHR mirrors can be custom size, shape, optimized for specific polarization, angle range. GDD and LIDT optimizations are also available upon request. Triple band reflection also available as well as broad-band BBHR options.

High power (high LIDT) Yb:YAG DBHR Mirrors

With specifically picked coating materials and carefully polished substrate, Alien Photonics Yb:YAG DBHR mirrors can withstand high energy pulses. This is very helpful in high power lasers.

Low GDD Yb:YAG DBHR mirrors

Alien Photonics Yb:YAG DBHR mirrors with optimized GDD can be efficiently used within ultrafast laser systems. Let us know if you need GDD optimization, as standard mirrors are not necessarily fully optimized.

Low loss | R>99.99%; R>99.95% | Yb:YAG DBHR Mirrors

Once substrates are very smoothly polished, these ultra-high reflection mirrors are formed using IBS coating technology. These mirrors are especially useful in research and industrial applications, where even smallest light loss is not allowed.

How Yb:YAG Dual-Band Mirrors are made ?

Process is very similar to other dual band DBHR mirrors and Laser Line (HR) mirrors. Alien Photonics DBHR mirror production starts from choosing window (substrate) and polishing it. Next step deposition of multilayer dielectric mirror coating. Once coated, these mirrors are inspected and shipped to customer (or stored).

Alternatives to Yb:YAG DBHR Mirrors

In some cases Yb:YAG DBHR mirrors can be replaced with two Yb:YAG HR mirrors and dichroic mirror (wavelength separator). However, more common practice is to replace them with broad band dielectric (BBHR) or even metallic (Au, Ag, Al) mirrors. When choosing between these two options Alien Photonics suggest to evaluate LIDT requirement, since broad band mirrors usually have quite low threshold. Reflection values should be evaluated as well.
