Excimer lasers are a family of pulsed lasers operating in the ultraviolet region of the spectrum. The source of the emission is a fast electrical discharge in a high pressure mixture of a rare gas (krypton, argon, or xenon) and a halogen gas (fluorine or hydrogen chloride). The particular combination of a rare gas and halogen determines the output wavelength, and in most commercial excimer lasers, the wavelength may be changed by refilling the laser with the appropriate gas combination.

Features of Excimer Laser for Sale
Wavelength Range: Excimer lasers output wavelengths in the 157-353 nm range, falling within the ultraviolet band. Typical wavelengths include 193 nm (ArF), 248 nm (KrF), and 308 nm (XeCl).
Pulse Energy and Power: Excimer lasers are characterized by high pulse energy (10-900 mJ) and high average power (up to several hundred watts or even higher). For example, some devices have a maximum single-pulse energy of 1200 mJ and a maximum average power of 60 W.
Beam Quality: The beam quality of excimer lasers is relatively poor, with an M² factor greater than 10, significantly lower than fiber lasers (M²≈1.05). However, its stability can be improved by employing techniques such as constant-temperature gas circulation modules.
Processing Resolution: Due to the short wavelength and high photon energy of excimer lasers, they offer high processing resolution, enabling micron-level and even nanometer-level processing precision.
Type of Excimer Laser for Sale
Electron-pumped excimer lasers
These lasers possess extremely high pulse energies (down to the kJ level), making them suitable for research under extreme conditions such as inertial confinement fusion (ICF).
Discharge-pumped excimer lasers
These lasers use high-voltage pulsed discharges (such as Blumlein circuits) to excite excimer gases, and are currently the mainstream technology in industrial and medical fields.
Optically pumped excimer lasers
These lasers use another laser (such as an Nd:YAG laser) to pump the excimer gas, achieving population inversion.
Applications of Excimer Laser for Sale
Semiconductor Lithography: Excimer lasers are crucial light sources in semiconductor lithography, especially the 248nm KrF and 193nm ArF excimer lasers, which are widely used in semiconductor mass production at various process nodes.
Flat Panel Display Manufacturing: In high-end flat panel display manufacturing, excimer laser annealing (ELA) uses a 308nm XeCl laser to transform the substrate from an amorphous silicon thin film to a high-quality polycrystalline silicon thin film, thereby improving TFT (thin-film transistor) performance.
Microfabrication: Excimer lasers also have wide applications in microelectronic packaging, fiber optic grating fabrication, micro-dicing, and micro-drilling. Their "cold processing" characteristic avoids the thermal effects and damage to surrounding tissues associated with infrared laser processing.
Ophthalmic Surgery: The 193nm ArF excimer laser is widely used in ophthalmic laser surgeries, such as corneal refractive surgery. Its single-photon energy is 6.4 eV, while the bonding energy between peptide bonds and carbon chains in human corneal tissue is only 3.4 eV.
Skin Disease Treatment: Excimer lasers can also be used to treat skin diseases such as vitiligo, achieving therapeutic effects by inducing apoptosis in diseased cells and promoting pigment synthesis.
Excimer laser is a new generation phototherapy treatment for conditions like psoriasis. Like previous treatment options for psoriasis, the Excimer laser relies on ultraviolet light to target psoriatic plaque and other problem areas, to heal the skin and reduce future outbreaks.
However, earlier versions of phototherapy relied on specialized lightboxes delivering UV light to the entire body. To utilize this therapy, the patient would disrobe, step into the box, and specialized light wavelengths were sent to the entire body.
Light therapy box treatments had an inherent disadvantage in that they treated the entire body. This was a problem for some patients, as healthy tissue was needlessly exposed to UV light, even though psoriatic plaque was only present on one area; like the elbows or the scalp.Further, UV light box treatments required more sessions.
The Excimer laser is a significant improvement on the UV light box treatments as it allows for precision targeting of psoriasis, without exposing healthy tissue to UV light.
Equipment Operation Safety
Electrical Safety
Excimer lasers require a high-voltage power supply of tens of thousands of volts. All high voltage must be released before maintenance to avoid the risk of electric shock.
The equipment should be equipped with an uninterruptible power supply (UPS) system to prevent data loss or equipment damage due to sudden power outages.
Regularly check the equipment's grounding status to ensure effective electrostatic discharge protection.
Gas Management
While rare gases (such as krypton and argon) are non-toxic, the concentration of halides (such as fluorine) in the air must be strictly limited (e.g., fluorine concentration must be below 1×10⁻⁸).
Regularly check the gas supply system to avoid leaks that could lead to poisoning or corrosion.
Temperature Control
The temperature of the discharge chamber gas directly affects the stability of laser energy. For example, the optimal operating temperature for a KrF excimer laser is approximately 50°C, and for an ArF laser, approximately 60°C.
Employ a high-precision temperature control system (such as a PID algorithm) to ensure temperature fluctuations do not exceed ±1°C to extend equipment life and improve output stability.
