Product description

MLase Excimer Laser MLI series


 Customer Benefits:

• Rigid, industry grade design

 ? High reliability

• Corona Preionization

 ? Homogeneous beam profile

• Modern Solid State Pulsed Power Module

 ? Immediate availability, no aging

• Tube Technology with higher gas capacity

 ? Tube all metal sealed for extended lifetimes

• Energy Monitor

 ? Energy stabilizing

• Compact Excimerlaser, Single Phase

 ? Easy to operate, easy to integrate


These compact stand-alone UV Lasers offer the best life times and reliability available on the market. With a homogeneous beam profile and energy stabilization, they are ideal for demanding applications. Simple connection via USB and control with the included software allow quick setup and easy Integration.

Customized OEM versions with individual features based on the standard products can also be offered. Integrators benefit from standardized interfaces and a strong local support team.

MLI models with the suffix "LC" also have the possibility of active water cooling (either via domestic water, or external heat exchanger, no DI water required) and thus allow a stable continuous operation at 100 % duty cycle.

Available wavelengths are 193 nm (gas: ArF - Argonflourid) and 248 nm (gas: KrF - Kryptonflourid). Other wavelengths are available on request.

Please consult Laser 2000 for support with planning and setting up an appropriate system for the supply of the laser gases.

System control is performed through a simple USB interface, RS232, or over a serial fiber optic connection. All changeable parameters (eg, repetition rate, pump voltage, etc.) and automatic gas exchange can be carried out using the software supplied.

Ophthalmic applications at Laser 2000:


Excimer Laser applications:

  • Eye surgery methods (ophthalmology) by means of LASIK (laser in situ keratomileusis) and PRK (photorefractive keratectomy), in which the shape of the cornea is changed in favor of the optical properties. For this ArF lasers are used at 193 nm.
  • Visual inspection and metrology
  • Optics and micro-optics inspection
  • Laser patterning and scribing
  • Micromachining brittle materials, such as ceramic, metal, or plastic
  • Laser ablation / Pulsed laser deposition (ICP-MS)
  • Dermatology, e. g. treatment of psoriasis and vitiligo with XeCl-lasers at 308 nm
  • Immersion Lithography
  • Writing masks
  • Direct wafer processing
