Dear Raad

There are some questions that I should ask before selecting any suitable laser and liquid.

What kind of Laser beam that you will use? What is the wavelength of that laser beam? Can this wave length penetrate the liquid layer to reach the GO? What will be the power required for such ablation?

In addition, I attach some links for papers discussing the laser ablation in aqueous colloids

Dear Mohammed S. Mohmoud,

I am very pleasures for this reply and helpful.

Nd-yag pulsing laser

1640 nm

yes it immersed, the layer water no more than 1.5 cm

1 j energy in nanosecond duration range of duration

regards

Raad

I understand that you want to disperse GO in water? or you want to reduce the GO by laser ablation with high peak power at very short time? I suggest to review some papers about the ablation techniques in liquid layers. My experience was in laser ablation but in vacuum for MgO reduction.

Best regards,
