Yes, tungsten needles can be used for microscale laser micromachining. Tungsten is a suitable material for this application because of its high melting point, which allows it to withstand the heat generated by the laser, and its excellent thermal conductivity, which helps to dissipate the heat and prevent damage to the needle. Tungsten needles can be used for a variety of laser micromachining applications, including drilling, cutting, and marking. The precise control provided by the laser allows for high precision and accuracy in microscale machining.
