Tattoo Removal: Type of Q-Switched Lasers and Beams

Laser treatment is a mainstay when tattoo removal is concerned. This treatment is considered to be less painful than some other methods.  Laser treatments are segmented. This means that the laser applied to remove a specific tattoo may be different from the one used to remove another type of tattoo. Some people may not know this, but there are different wavelengths that can be used to remove tattoo colours.

There is a reason why laser beams are very useful in removing tattoos. These tattoos are visible on the skin because the ink cannot be broken down easily. The laser removal tools work through the decomposition of ink in the skin. This device breaks up the ink in the skin for easier processing and disposal.

The article gives you an idea of the various types of Q-switched laser beams. You will also get to see the functions of each beam on the skin during operation.

The Q-Switched laser beams are the most used in the tattoo removal market. This is because the laser beam produces the best results with little side effects. Here are some of the Q-switched laser beams currently in the market:

Q-Switched Ruby:

The Ruby produces a red beam which enhances the decomposition of very dark-coloured tattoos. This fast acting laser removes the tattoos well into the dermis. The results are mostly favourable. Also, fewer visits are required to get the skin healed depending on the size of the tattoo.

Q-Switched Frequency-Doubled YAG:

This laser produces a very direct effect on the ink in the skin. This laser produces a green beam. It is very effective in erasing tattoos that were designed with a range of bright colours. This laser is also very effective in taking off some unwanted spots in the body. The wavelength from the laser easily absorbs into the skin and breaks down the pigment in the skin. This makes it easier for the body to process the ink and pass it out.

Q-Switched YAG:

The Q-switched YAG is built with a very low light which is difficult to see with the naked eye. This laser is best for customers with dark skin. This laser has a low absorption ratio to the melanin content of the body. For those who may not know what melanin is – it’s what gives the human skin colour. This is why it is good for darker pigments.  This laser is very suitable for darker skin. It is also suitable for dark ink pigments.

Q-Switched Alexandrite:

The Q-switched Alexandrite creates a red beam and is suitable for small-sized tattoos. This laser is also very suitable for dark skin. This is because the laser is absorbed into the melanin at a slow rate. This prevents the incidence of any unwanted skin problems. This laser is popular because it has a lesser wavelength which works well on small tattoos made with dark ink.


The Q-switched lasers continue to gain prominence in the tattoo removal market. All of these beams are available at the nearest tattoo Sydney removal service you desire. With the help of a trained expert in tattoo removal, your skin will regenerate very well. It is important to note that the results you experience depend on the individual that is in charge of the removal.

Does Mock Exam Help in Preparing for Exams?

For many examinations — both online and paper-based — there are sample, practice or mock examinations that are meant to help you prepare for the real exams. Whichever name you call it, the purpose of the examinations are clear and that is why it surprising when some people still ask if they are useful. I will go straight to the answer and tell you, yes they are very helpful and I will tell you why.

Firstly, when we talk about mock exams, in this context, we are not referring to the general school exams but the “special” examinations like GMAT, GRA, SAT, TOEFL, IELTS and so on. In Nigeria, examinations such as WAEC, NECO and JAMB would be perfect examples. These exams are generally used for admission into schools or as proof of proficiency of a language.

For the purpose of this article, I will use an example of how JAMB mock exam is helpful to candidates who are writing JAMB UTME. Before I proceed, I should let you know that JAMB stands for Joint Admission and Matriculation Board, while UTME stands for Unified Tertiary Matriculation Examination. The UTME is the entrance examination for admission into Nigerian universities. JAMB is the body that has the constitutional duty to conduct UTME.

How Mock Exam Help in Preparing for Exams

  1. Mock examinations like that by JAMB helps candidates familiarise themselves with the examination. Mock exams present the rare opportunity for candidates to write an exam that is closest to what they will face in the real examination. These include knowing the format of the exam, the time set for completion and so on.
  2. Examinations like these also help candidates to acquaint themselves with the examination conditions. For examples, I have met candidates who cannot sit through a four-hour long test, therefore, they become restless after sitting through a couple of hours of test. Taking a practice test will help them realise what they signed up for and working towards an endurance level that would take them through such exams.
  3. Lastly, mock exams help candidates to know their standing (i.e. level of preparedness) and give them an idea of the task they have ahead. For example, if a candidates scores low in a mock exam, it is an indication that they might not do well in the real examination.

For candidates who want to write JAMB, they need to register for JAMB UTME, then register for the UTME mock exam before writing the final exam. This has helped many candidates achieve success in the exam.

In conclusion, even though I have used a relatively unfamiliar examination as an example, the reasons I gave in favour of mock exams are applicable to other exams such as GMAT, GRE, TOEFL, IELTS, etc.

Wishing you the very best as you prepare for your forthcoming examinations.
