1What is the primary difference between Laser and Intense Pulsed Light (IPL) technologies?

A.Laser is monochromatic, coherent, and collimated, whereas IPL is polychromatic, non-coherent, and divergent.

B.IPL is monochromatic and coherent, whereas Laser produces a broad spectrum of light waves.

C.Laser light is divergent and targets multiple chromophores, whereas IPL is highly focused on a single wavelength.

D.IPL uses sound waves to target tissue, whereas Laser uses electromagnetic radiation.

Explanation: Laser light consists of a single wavelength (monochromatic), waves in phase (coherent), and travels in a straight line (collimated). In contrast, IPL produces a broad spectrum of wavelengths (polychromatic) that spread out (divergent) and are out of phase (non-coherent).

2Which wavelength is associated with an Alexandrite laser?

A.1064 nm

B.755 nm

C.810 nm

D.694 nm

Explanation: The Alexandrite laser operates at a wavelength of 755 nm, which is highly absorbed by melanin, making it excellent for hair removal in skin types I-IV.

3What does the wavelength of a laser determine in light-tissue interactions?

A.The rate of machine cooling and target spot size.

B.The depth of penetration and the specific chromophore targeted.

C.The speed at which the laser pulses are delivered to the skin.

D.The overall diameter of the optical fiber cable.

Explanation: Wavelength determines both how deep the light penetrates into the skin (longer wavelengths penetrate deeper) and which chromophore (melanin, haemoglobin, or water) absorbs the energy.

4What is the principal target chromophore when performing laser hair reduction?

A.Melanin in the hair shaft and follicle

B.Haemoglobin in the dermal papilla capillary network

C.Water in the surrounding follicular cells

D.Collagen in the extracellular matrix of the dermis

Explanation: Melanin located within the hair shaft and root sheath is the primary chromophore that absorbs light energy, converting it to heat to destroy the germinating hair cells.

5What does the principle of selective photothermolysis state?

A.Light must be reflected off the epidermis to prevent thermal damage to the dermis.

B.A specific wavelength of light must be absorbed by a target chromophore and converted to heat, damaging it without affecting surrounding tissues.

C.Any light source can be used to heat all skin structures equally to stimulate cellular turnover.

D.Heat must be applied using physical contact to cool the epidermis before light emission.

Explanation: Selective photothermolysis requires using a specific wavelength, pulse duration, and fluence to selectively target and thermally damage a chromophore while sparing the surrounding tissue.

6How is fluence defined in laser and IPL treatments?

A.The wavelength of the emitted beam measured in nanometres.

B.The energy delivered per unit area, measured in Joules per square centimetre (J/cm²).

C.The diameter of the laser beam at the skin's surface measured in millimetres.

D.The duration of the light pulse measured in milliseconds.

Explanation: Fluence refers to the energy density of the light beam, calculated as energy (Joules) divided by the area of the spot size (cm²).

7What is the relationship between spot size and laser penetration depth?

A.A larger spot size increases depth of penetration by reducing optical scattering.

B.A smaller spot size increases depth of penetration by focusing light into a narrower beam.

C.Spot size has no effect on the depth of penetration.

D.A larger spot size limits penetration depth to the epidermis only.

Explanation: Larger spot sizes suffer less lateral light scattering in the dermis, allowing a greater proportion of the energy to penetrate deeper to reach deep hair follicles.

8In laser physics, what is 'thermal relaxation time' (TRT)?

A.The time required for the laser device's internal cooling system to cool down between treatments.

B.The time taken for a target structure to lose 50% of its absorbed heat to surrounding tissue.

C.The time required for the patient's skin to feel cool after active ice pack application.

D.The time delay between pressing the handpiece trigger and light emission.

Explanation: Thermal Relaxation Time (TRT) is the time it takes for the targeted chromophore to dissipate 50% of its heat energy to the surrounding tissue. To prevent collateral damage, the pulse duration should generally be shorter than the target's TRT.

9Why is pulse duration (pulse width) a critical parameter in laser treatments?

A.It controls the electrical consumption of the salon's power grid.

B.It determines the rate of thermal energy delivery and prevents damage to surrounding tissue relative to the target's TRT.

C.It alters the wavelength of the light being emitted by the flashlamp.

D.It determines the size of the glass treatment window on the handpiece.

Explanation: Pulse duration determines how long the light is in contact with the skin. Matching the pulse duration to the target's thermal relaxation time ensures efficient heating of the target while protecting surrounding tissue.

10Which wavelength penetrative depth makes it safest for hair removal on Fitzpatrick Skin Type VI?

A.755 nm (Alexandrite)

B.1064 nm (Nd:YAG)

C.694 nm (Ruby)

D.532 nm (KTP)

Explanation: The Nd:YAG laser operates at 1064 nm. Its longer wavelength penetrates deeply to bypass epidermal melanin (which has lower absorption at this wavelength), making it the safest option for dark skin types.
