What is the Nd YAG laser absorbed by?

What is the Nd YAG laser absorbed by?

The radiation is more readily absorbed by dark tissue. Blue or black pigmentation enhances Nd : YAG absorption, whereas pale colors enhance its penetration. Nd : YAG radiation penetrates tissues to a depth of 2 to 6 mm and provides good homeostasis for blood vessels up to 0.5 cm in diameter.

What is the difference between ND YAG and Er YAG?

Er:YAG lasers typically emit light with a wavelength of 2940 nm, which is infrared light. Unlike Nd:YAG laser, the output of an Er:YAG laser is strongly absorbed by water.

What is CR YAG?

Cr:YAG is an excellent passive Q-switch crystal, for 0.8 to 1.2 µm lasers: Nd:YAG, Yb:YAG. Cr:YAG is chemically stable, durable, UV resistant, good thermal conductivity and high damage threshold. Cr:YAG can also be used as a laser crystal tuable at 1340 – 1580nm.

Does Nd:YAG hurt?

Side effects from Nd:YAG laser treatment are usually minor and may include: Pain during treatment (reduced by contact cooling and if necessary, topical anaesthetic) Redness, swelling and itching immediately after the procedure that may last a few days after treatment.

Where is Nd:YAG most commonly used?

Nd:YAG lasers emitting light at 1064 nm have been the most widely used laser for laser-induced thermotherapy, in which benign or malignant lesions in various organs are ablated by the beam. In oncology, Nd:YAG lasers can be used to remove skin cancers.

What does Er YAG stand for?

Erbium YAG (Er:YAG) lasers are solid-state lasers whose lasing medium is erbium-doped yttrium aluminium garnet (Er:Y3Al5O12).

What is the difference between IPL and YAG laser?

IPL operates differently to laser as it sends out multiple rays of light at different wavelengths at the same time. While the Nd:YAG targets the area beneath the epidermis, IPL targets above and below in a fragmented approach.

How effective is Nd:YAG laser?

Previous studies with the Nd: YAG laser in skin phototypes IV–VI have shown a hair reduction varying from 23 to 33% after a single session,[1,2,3,14] 58 to 62% after three sessions[13] and 50 to 100% after 5–7 sessions[4,8,9] respectively at 4–12 weeks follow-up.

Which is the normal condition in Nd:YAG laser?

Under normal conditions, the Nd:YAG laser oscillates on a transition in the near infrared at 1064 nm, and this is the excitation line that is used in most commercial Fourier Transform Raman spectrometers. The gain medium is a crystal of yttrium aluminium garnet (Y3Al5O12, YAG) doped with ca.

What is Er YAG laser used for?

Erbium:yttrium-aluminum-garnet (Er:YAG) laser skin resurfacing is an effective technique for minimally invasive and effective management of a number of cutaneous conditions and lesions. Its main indications include treatment of photoaging, rhytids, and solitary benign and malignant cutaneous lesions.

What is the Nd YAG laser absorbed by? The radiation is more readily absorbed by dark tissue. Blue or black pigmentation enhances Nd : YAG absorption, whereas pale colors enhance its penetration. Nd : YAG radiation penetrates tissues to a depth of 2 to 6 mm and provides good homeostasis for blood vessels up to…
