RFH S9 series laser features fast speed, high precision and high stability, making it an indispensable part in laser etching technique used for logo identification. 

355nm UV laser has a very tiny focal spot and small heat affected zone with almost no damage by the heat effect, so it is often called as cold light source. Because of this, deformation or burning of the materials caused by heat effect can be avoided.

During the coronavirus, RFH S9 series 3W-5W UV laser is popular for N95 face masks marking date code.

S9 series uv laser characteristics：

1. Laser wavelength at 354.7nm,  repetition rates cover a wide range(single pulse to 200kHz）; laser power ranging from 3.0w-5.0w;

2. Exceptional beam quality (M²<1.2) ，absolutely assured in all repetition rates; relatively short pulse width <12ns@30 with little heat transfer to surrounding material; perfect beam spot quality(Beam Circularity>90%)

3. Unique Q-switching technology, adapts a variety of control requirements of laser applications;

Online refreshment for harmonic coupling technology;Excellent long term power stability

4. Digital control technology for the driver, enables user to command through RS232

5. This laser adopts one - style design with compact and reasonable structure, easy installation.

6. Industrial production process control technology,provides quality stable products.
