Based on the specific configuration for this class of Nd:YAG laser, the system operates with a highly precise set of technical parameters. It features a fixed pulse duration of 5 nanoseconds (ns), an adjustable frequency range of 1 to 10 Hz, and an optional spot diameter ranging from 2 mm to 10 mm.
Core Insight: These specifications describe a system designed for high-peak-power delivery, where the extremely short pulse duration (5ns) allows for intense energy impact while the adjustable frequency and spot size provide the operator with control over treatment speed and coverage area.
Detailed Breakdown of Technical Parameters
To understand how this laser performs in practical applications, we must analyze how these three specific variables interact.
Pulse Duration Dynamics
The Power of 5 Nanoseconds The pulse duration is fixed at 5ns. This places the laser in the nanosecond domain, meaning the energy is compressed into an incredibly short timeframe.
Implications for Impact A 5ns pulse creates a photo-acoustic effect rather than a purely thermal one. This allows the laser to shatter target materials (such as pigment particles) effectively without transferring excessive heat to the surrounding area.
Operational Frequency
Adjustable Repetition Rate The system offers a frequency adjustable between 1 Hz and 10 Hz. This refers to the number of laser pulses fired per second.
Operator Control At 1 Hz, the laser fires once per second, allowing for deliberate, precise placement. At 10 Hz, the laser fires ten times per second, enabling a "gliding" motion for faster coverage of larger areas.
Spot Diameter Versatility
Variable Beam Size The spot diameter is the physical size of the laser beam as it hits the target. This system offers an optional range from 2 mm up to 10 mm.
Coverage vs. Precision A 2 mm spot size allows for work on very fine, detailed targets. Conversely, expanding the spot to 10 mm allows the user to treat larger surface areas much more rapidly.
Understanding the Trade-offs
While these specifications offer versatility, they also introduce physical trade-offs that must be managed during operation.
Spot Size vs. Energy Density (Fluence)
There is an inverse relationship between spot size and energy density. As you increase the spot diameter from 2 mm to 10 mm, the energy is spread over a larger area.
Unless the total energy is increased proportionally, a larger spot size will result in a weaker impact per square millimeter.
Frequency vs. Precision
Running the system at the maximum 10 Hz frequency increases speed but requires faster operator reaction times.
At higher speeds, the risk of overlapping pulses or missing areas increases. Lower frequencies (1-3 Hz) are generally safer when high precision is required.
Making the Right Choice for Your Goal
Selecting the correct settings within these specifications depends entirely on your immediate objective.
- If your primary focus is high-intensity impact: Use a smaller spot diameter (closer to 2 mm) to maximize the energy density (fluence) delivered by the 5ns pulse.
- If your primary focus is treating large areas quickly: Increase the spot diameter toward 10 mm and raise the frequency to 10 Hz to maximize coverage speed.
Balancing the spot diameter against the frequency allows you to optimize the system for both detailed work and broad application efficiency.
Summary Table:
| Parameter | Specification | Impact on Treatment |
|---|---|---|
| Pulse Duration | 5 Nanoseconds (ns) | Photo-acoustic effect shatters pigment with minimal heat damage. |
| Frequency | 1 - 10 Hz | Adjustable speed; higher Hz allows for faster coverage of large areas. |
| Spot Diameter | 2 mm - 10 mm | Versatility for fine precision (2mm) or rapid large-area treatment (10mm). |
| Energy Delivery | High-Peak-Power | Ensures intense impact necessary for effective pigment and tattoo removal. |
