50% Er:YAG laser rod with high doping concentration of Er3+ ions
With wavelength of 2936nm, the main feature is very high absorption in water and hydroxyapatite. With this in mind it is clear that Er:YAG crystal laser rods are mostly applicable for the manufacturing of laser that serve in dental surgery and aesthetic surgery.
These Er:YAG crystal laser rods have a very high doping concentration of Er3+ ions which are typically used for lasing at 2936 nm.
On the other hand, Low-doped Er:YAG laser crystals are used for producing an eye-safe radiation at 1645 nm by in-band pumping with semiconductor laser diodes at 1,5 microns. The result is low thermal load corresponding to low quantum defect using this kind of scheme.

Here are 10 similar or competing products that are in top demand today, reflecting the diversity and specialization of the laser and optics market:
1. Er,Cr:YSGG Laser Rods
This is a direct competitor to Er:YAG. The YSGG (Yttrium Scandium Gallium Garnet) crystal, co-doped with erbium and chromium ions, lases at a slightly different wavelength (2790 nm). It is a top choice in dentistry and medicine for similar tissue ablation procedures.
2. Nd:YAG Laser Rods
This is a classic and versatile gain medium that lases at 1064 nm. While not used for the same ablative applications as Er:YAG, it is in high demand for dermatology and aesthetics for non-ablative treatments such as hair removal, tattoo removal, and skin rejuvenation.
3. Tm:YAG (Thulium-doped YAG) Laser Rods
Thulium-doped YAG lases in the 2-micron range (around 2015 nm). This wavelength is also strongly absorbed by water, but less than the 2940 nm of Er:YAG, allowing for deeper penetration. It is in high demand for surgical applications, particularly urology and lithotripsy (stone fragmentation).
4. Ho:YAG (Holmium-doped YAG) Laser Rods
Similar to Tm:YAG, Ho:YAG lasers operate at a wavelength of 2120 nm and are used for ablative surgical procedures. Their high demand comes from their use in orthopedic, general surgery, and especially urology for kidney stone treatment.
5. Yb:YAG (Ytterbium-doped YAG) Laser Modules
Yb:YAG has largely replaced Nd:YAG for high-power, industrial applications like cutting and welding. Its high efficiency and low thermal load make it highly demanded for high-power laser systems.
6. Diode-Pumped Solid-State (DPSS) Laser Modules
This is a broader category of products that often contain Nd:YAG or Nd:YVO4 crystals. These modules are in top demand because they are highly efficient and reliable, serving as the workhorse for laser marking, micromachining, and other industrial applications.
7. CO2 Laser Tubes
While not a solid-state rod, a CO2 laser is a major competitor for ablative applications. Operating at 10,600 nm, it is also strongly absorbed by water and used for skin resurfacing, surgical procedures, and industrial cutting of non-metals. Its high demand comes from its long history and versatility.
8. Fiber Laser Gain Fibers
Fiber lasers, which use rare-earth-doped optical fibers as their gain medium, are an increasingly dominant technology. They are highly efficient, have a small footprint, and offer excellent beam quality, making them a top choice for industrial marking, welding, and medical applications.
9. Femtosecond Laser Modules
For high-precision surgical and micromachining applications, femtosecond lasers are in high demand. They operate on a principle called “cold ablation,” where the ultra-short pulses vaporize material with minimal heat transfer to the surrounding area. This allows for extremely precise cuts, which is crucial in delicate procedures like ophthalmology.
10. Sapphire and Ti:Sapphire Laser Rods
These are specialized gain media used for tunable, ultrafast lasers. Titanium-doped Sapphire (Ti:Sapphire) is in high demand for cutting-edge scientific research and medical imaging because it can be tuned over a very wide wavelength range and is the standard for generating femtosecond pulses.
