What is a Yb laser?
What is a Yb laser?
Thorlabs’ Y-Fi™ Femtosecond Ytterbium Fiber Laser is a high peak power, NIR laser that emits clean, ultrafast pulses centered at 1035 nm.
What is Nd:YAG used for?
Nd:YAG, or neodymium-doped yttrium aluminum garnet, is one of the more advanced types of laser technology now commonly used for the treatment of a wide range of skin and eye disorders. It is marketed under different brand names, including Cutera, RevLite Q-Switched, and Fotona, among others.
What is the frequency of Nd:YAG laser?
The most common Nd:YAG emission wavelength is 1064 nm. Starting with that wavelength, outputs at 532, 355 and 266 nm can be generated by frequency doubling, frequency tripling and frequency quadrupling, respectively. Other emission lines are at 946, 1123, 1319, 1338, 1415 and 1444 nm.
What wavelength is a YAG laser?
1064 nm
The Nd:YAG lasers operate at a wavelength of 1064 nm. These lasers are fiberoptic-delivered contact lasers that generate a free-running pulsed beam of energy. This pulsing mechanism is more sophisticated and the potential for heat penetration even greater than with a diode laser.
What type of laser is YAG?
YAG laser: A type of laser emitting near-infrared light used to cut or ablate tissue by conversion of the light into heat upon absorption by the tissue.
What class is Nd:YAG laser?
Class 3 b
Self-Assembled and Modified Lasers
| Laser type | Wavelength (nm) | Class 3 b (W) |
|---|---|---|
| Nd:YAG | 1064 | > Class 1 but <0.5 |
| He-Ne | 1080 | |
| 1152 | ||
| InGaAsP | 1310 |
Is Nd:YAG a diode laser?
These laser diodes are sometimes called “YAG diodes” or even Nd:YAG lasers, but the terminology is inappropriate and is used to draw attention to the similarity between their emission wavelength and that of the Nd:YAG laser (1064nm).
What wavelength is YAG?
The Nd:YAG laser was the first type of laser used in urological practice. It uses a crystal of neodymium that produces a light invisible at a continuous wavelength of 1064 nm.
What is the average power of a YAG laser?
3) H. Bruesselbach and D. Sumida, “69-W-average power Yb:YAG laser,” Opt. Lett. 21, 480 (1996). Orlando, FL.
Are Yb3+ doped materials suitable for high energy 1 µm lasers?
As a result, Yb 3+ doped materials have spectroscopic and laser properties that are advantageous for high energy 1 µm laser systems. In particular, Yb 3+ doped materials should not suffer from concentration quenching, upconversion, or excited state absorption.
What are the dopant levels of YAG?
The dopant levels range between 0.2-30% of replaced yttrium atoms. Yb:YAG has very low fractional heating, very high slope efficiency, and no excited-state absorption or up-conversion, high mechanical strength and high thermal conductivity.
What is the difference between YAG and Nd3+ YAG?
Yb 3+ :YAG also has a broad pump line at 940 nm that is 10 times broader than the 808 nm pump line in Nd 3+ YAG making the system less sensitive to thermal drift of the pump diodes wavelength.
