Cosjet ATR-S

The Gold Standard in Q-Switched Laser Technology
For the past 15 years Wontech have been producing wonderful Q-Switched lasers, the ATR series has remained the original and best Q-Switched Laser Technology available. With its outstanding results, great design and reliable technology, it is currently rewriting what we can do with a Q-Switched laser for the treatment of pigmented lesions.

High Power Output
A continuous and consistent energy output with stable power is made possible by a newly-designed laser head. This allows the user the confidence in power delivery throughout the whole treatment.
The ATRS energy output is 1,600mJ @ 1064nm and 500mj @ 532nm
- 3,500mJ @ Genesis.

PTP Mode (Photoacoustic Twice Pulse)
The ATRS adopts the Photoacoustic Twice Pulse mode, which constantly delivers twin-pulsed, high-output energy at very short intervals. As a pulse is divided into two, a lesser risk for injury to the surrounding tissue, lesser pain during treatments and a quicker healing time is made possible. Treatments with PTP mode are also associated with less hypopigmentation, post-inflammatory hyperpigmentation and other adverse effects.
PTP mode provides a more comfortable experience for the patient compared to single pulses of energy.
New Laser hand pieces 660nm and 585nm wavelengths allow the ATR to treat stubborn and difficult to remove light green and light blue ink.


(Optional) Fractional Hand Piece

An optional fractional hand piece with a spot size adjustable from 5×5 – 9x9mm decreases thermal damage in the dermis and allows for quicker healing and recovery time.
Perfect Top Hat Beam Profile
The ATR has a precise top hat beam profile allowing it’s super high speed light to smash tattoo ink. The Top Hat Beam profile delivers energy squarely without a dip or rise at any point during treatment. Unlike other Q-Switched lasers on the market, the ATR produces an ongoing stable beam profile allowing it to successfully smash and breakdown tattoo inks consistently.


The ATRS has Genesis mode – the pulse duration is increased to 320ns of light speed. This allows the ATRS to perform Laser Genesis which is a popular treatment for skin rejuvenation and collagen stimulation for improvement of the skin’s tone and texture.
