An Er:YAG laser ( erbium-doped yttrium aluminium garnet laser, erbium YAG laser) is a solid-state laser whose active laser medium is erbium -doped yttrium aluminium garnet (Er:Y 3 Al 5 O 12 ). Er:YAG lasers typically emit light with a wavelength of 2940 nm, which is infrared light .
We have two Er:Glass lasers: one of 1540 nm and one of 1565 nm wavelength. The laser emits energy in microbundles of 300 microns diameter (0.3 mm) (laser of 1540 nm), or 110 microns (0.11 mm) (laser of 1565 nm). These bundles cause a denaturation of the dermis without removing the epithelial surface. Each column of the denatured dermis will be ...
This study investigated the feasibility of using an Er:YAG laser to pretreat glass-ceramic surface and evaluate the effect of the treatment on the bonding strength and marginal adaptation between glass-ceramic and dentin. Glass-ceramic samples (CEREC Blocs) and third molars were cut into 6 mm × 6 mm × 2 mm plates.
The interest in Yb-sensitized Er-activated glass lasers is mostly associated with the eye-safety of their wavelength ( λ ~1.53–1.56 μm) corresponding to 4 I 13/2 – 4 I 15/2 Er 3 + ion transition. The chapter first discusses the design of flashlamp pumped Er:glass lasers. Then the typical configurations of diode pumped Er lasers are considered.
The laser wavelength was blue-shifted from 1.6 to 1.55 μm when the OM transmissivity was increased from 1.7% to 5.8%. This phenomenon is attributed to the gain characteristic of the Er 3+ /Yb 3 ...

1535nm Er Glass Eye-Safe Solid-State Microchip Laser — Ultra-Compact DPSSL for Ranging Finder. The wavelength of 1535nm is just in the position of the human eye and the atmospheric window, so it has been widely concerned in the fields of laser ranging and electronic communication.
Key Features: 1.54µm wavelength. Up to 10mJ average output energy. Up to 30Hz repetition rate. Active or Passive Q-switching. Up to 40ns pulse width. 4mm beam <5mrad divergence. -40 o C to 65 o C. Forced air cooling.
Depending on the glass composition, the transition wavelength is usually somewhere between 1.53 and 1.6 μm. Because that transition is a quasi-three-level transition , erbium-doped laser and amplifiers require a significant excitation density of the erbium ions, and erbium lasers typically exhibit a high threshold pump power .

The Er:Yb co-doped glass laser configuration is shown in Figure 1. The laser resonator consisted of an output coupler mirror, a flat high reflector (HR) at 1.5 µm and a 5 mm thickness uncoated Er:Yb co-doped glass. The HR mirror was fixed to a motor shaft, which worked as an optical Q-switch. The laser gain medium was supported by a brass holder
The results revealed that Er:YAG laser pretreatments at 300 mJ and 15 Hz, 400 mJ and 15 Hz, and 500 mJ and 15 Hz coarsened the surface of glass–ceramic. Among the different energy levels, 300 mJ and 15 Hz and 400 mJ at 15 Hz produced scattered, irregular, and uneven crater structures on the ceramic surface and ultimately led to poor ...
