Laser Power Supply (CO2 Laser Power Supply)
The laser power supply is a crucial component of laser systems, playing a pivotal role in laser technology applications. Its quality and performance directly impact the efficiency and stability of laser devices. Some key features to look for in laser power supplies include high ignition success rates, safety, unique sleep functions, and comprehensive protection mechanisms. Different laser power supplies are suitable for various types of lasers, and they significantly influence laser performance and lifespan.
For CO2 laser power supplies, replacement is recommended approximately every two years due to factors like capacitors, resistors, inductors, transistors, and heat sinks affecting their quality and performance. The materials, manufacturing processes, and quality of electrical components like capacitors and resistors directly influence laser power supply performance. Transistors are critical for determining laser output power and waveform shape, impacting laser efficiency and stability. Heat sinks are essential for ensuring laser power supply stability, with their manufacturing processes, heat dissipation effectiveness, and quality affecting laser performance and lifespan.
Startnow offers laser power supplies under its own brand as well as the Hongyuan(HY) brand, which are essentially the same. CO2 laser power supplies have a broad output power range of 40W to 180W, suitable for different laser tube power requirements based on customer needs.

Laser Tube (CO2 Laser Tube)
A sealed CO2 laser tube consists of several components, including a discharge tube, water cooling tube, gas storage sheath, return gas tube, discharge electrode, full reflective mirror, and output mirror, arranged from the inside out. The working principle involves high-voltage discharge exciting high-concentration CO2 gas to produce a 10.6μm wavelength laser.
Laser tube selection primarily depends on laser power. Common models available include 30W, 40W, 45W, 50W, 55W, 75W, 90W, and 100W, with variations in length and diameter. For instance, a 40W laser tube is typically 700mm long with a 50mm diameter, while a 100W tube is 1450mm long with an 80mm diameter.
Laser tube quality is determined by laser power, beam quality, stability, and lifespan. Different materials and performance factors affect laser tube power and beam quality. Tubes with poor stability are prone to issues like gas leaks and spontaneous ruptures. Since laser tubes are consumables in laser processing equipment, their lifespan is a critical consideration for users.
Proper maintenance is essential for laser tubes to ensure a longer lifespan. Ensure a stable operating environment with consistent power voltage, avoid working in environments with significant vibrations or moisture (as humidity can cause high-voltage arcing), maintain appropriate laser current levels, ensure an adequate and clean water supply (temperature between 5-25°C), and regularly replace the circulating water, preferably with deionized water. Periodically clean the focusing lenses to keep them free of debris.
Laser tubes have a limited lifespan and need timely replacement once they reach their expiration. For Startnow laser tubes, customers can directly contact us for replacements within the warranty period.
Usage Guidelines:
- Operate under proper water cooling conditions.
