LED-pumped Nd:YAG Gain Module

🔋 Why Choose LED Pumping for Your Laser System?

🌟 Key Advantages of LED Pumping

✅ Ultra-Long Lifetime
Operates for 10,000+ hours without degradation—far outlasting flashlamps and laser diodes.
✅ Superior Reliability
No catastrophic failure modes. LEDs degrade gradually and predictably.
✅ Low Thermal Load
Gentle, uniform pumping reduces thermal stress on your gain medium and optics.
✅ Cost-Effective
Lower upfront cost and minimal maintenance = reduced total cost of ownership.
✅ Speckle-Free Output
Ideal for medical imaging, Material processing, and high-uniformity applications.
✅ Eco-Friendly & Safe
No toxic materials, no high-voltage drivers, and dramatically lower power consumption.

High-Power Laser Solutions for Industry, Medicine, and Research

Laser Types by Operation Mode

1. CW (Continuous Wave) Lasers

Emit a constant, uninterrupted laser beam.
Ideal for cutting, welding, and continuous illumination applications.
Example: Nd:YAG CW Laser @ 1064 nm

2. QCW (Quasi-Continuous Wave) Lasers

Operate in long pulse modes (microseconds to milliseconds).
Provide high peak power while reducing thermal load.
Commonly used in surgical tools and industrial machining.

3. Q-Switched Lasers

Generate short, high-energy pulses by rapidly switching the quality factor (Q) of the laser cavity.

• Electro-Optic (EO) Q-switched

Delivers precise, flat-top beam profiles.
Controlled via external voltage signal.
Suitable for micromachining and marking.

• Acousto-Optic (AO) Q-switched

Uses sound waves to modulate Q-switching.
Provides medium pulse energy and moderate complexity.
Good for LIDAR, range finding, and scientific applications.

• Passive Q-switched

Uses saturable absorbers (e.g., Cr:YAG) for automatic pulsing.
Compact and cost-effective, no external electronics required.
Ideal for portable and compact laser devices.

4. Amplifier Lasers

• Regenerative Amplifier (RGA)

Used in ultrafast and high-intensity systems.
Amplifies femtosecond or picosecond seed pulses with high gain.
Suitable for scientific research, nonlinear optics, and THz generation.

• Laser Amplifier Modules

Designed to boost the energy of low-energy seed lasers.
Operate in Gaussian beam mode.
Often used in multi-stage laser systems for material processing and scientific applications.

LED-Pumped Laser Stability & Applications

🔧 Burn-In Test – 1 J QCW Laser (8 Hours)

The burn-in test evaluates the reliability of a 1 J QCW laser by operating it continuously for 8 hours at 10 Hz. The test checks for output stability, thermal management, and component durability under sustained conditions.

Key parameters like pulse energy, diode current, and temperature are monitored. The laser must maintain <±0.6% energy fluctuation with no power drops or failures. This ensures the system is stable and ready for long-term use.
