Laser Optics Systems

INNOVAVENT – Laser Optics Systems are of modular design and are designed in close cooperation with users and system integrators. The products range from low-budget optical systems to create a line focus up to complex laser optical subsystems including laser, homogenizing optics, imaging p-lens and beam diagnostics.

VOLCANO Laser Optics includes cylindrical focusing and imaging of Gaussian beams. Long lines up to
200 mm, as sharp as FWHM <10 µm in the scan axis, provide a typical blur of 0.1-1 mm in the long dimension. The cylindrical imaging is done by the INNOVAVENT FALCON p-lens family.
The VOLCANO Laser Optics is operated with 515 nm JenLas^® ASAMA 80-8. This laser allows to adjust the pulse length between 300 ns and 1,200 ns by software setting and its beam properties are optimum to form a laser line.

The second product group, LAVA Laser Optics, employs the high repetition-rate 515 nm
JenLas^®ASAMA 100-1 operated at 50 kHz or 100 kHz at low pulse energy (1 mJ oder 2 mJ). The pulse length setting is limited within 300 ns to 600 ns. LAVA Laser Optics always includes a spherical imaging p-lens. The CaF₂ high performance p-lens EAGLEplus is a key module, which provides thermal-lens-free diffraction limited 2-dimensional imaging of lines within a field of view of 10 mm.

The new LAVA CW Laser Optics was introduced in 2009. These set ups include the CaF₂ EAGLEplus p-lens and the continous wave JenLas^® D2 laser technology. The second harmonic 532 nm Nd:vanadate thin disk laser emits up the 8 W multimode light power. Up to 160 W modules are configured by multiplexing and optical fiber transport provides the beam to homogenizer optics to form a laser line. The LAVA CW laser optics provides very high power stability and homogeneity in the generated Gaussian line focus.

LAVA 64CW: 64 W, 100 kW/cm², 1.2 mm line length, FWHM=30-35 µm, 1 σ <=1.5 % homogeneity.
