355nm UV lasers are essential in PCB marking, DNA sequencing, glass etching, and OLED repair, thanks to their high energy density and ultra-fine precision.
But did you know?
Only 10% of the input power becomes UV light — the other 90% turns into heat.
That’s why precision cooling is critical for stable laser operation and long-term reliability.
How Does It Work?
The 355nm UV laser is created through multiple nonlinear processes using:
* Nd\:YAG crystals
* KTP or BBO frequency doubling crystals
* SFG technology for wavelength conversion
Choosing the Right Chiller
For a 30W UV laser, expect 270W of heat to be generated. You’ll need:
✔ Cooling capacity ≥ 540W
✔ Temperature control precision: ±0.1°C
✔ Flow rate: ≥10L/min
✔ Eco-friendly refrigerant (R134a / R410a)
Recommended: Coolingstyle Q580 Chiller
Compact and powerful, the Q580 supports 5W–30W UV lasers with:
✅ 580W cooling power
✅ ±0.1°C accuracy
✅ 24L/min flow rate
✅ Energy-saving DC inverter compressor
Proper cooling = Longer laser lifespan + Lower maintenance costs.
Make the smart choice for your 355nm UV laser system.
