EdgeWave is the pioneer in the conception of INNOSLAB technology and now leads the international field in this new area of technology. The major innovation of INNOSLAB technology relies on a slab-shaped laser crystal. It has only two polished end faces for passing the pump radiation and a laser beam and is partially and longitudinally pumped with diode lasers. Its two large faces are thermally contacted to heat sinks for effective cooling. In this design the waste heat flow is one dimensional.

EdgeWave is the pioneer of novel micro glass processing based on forwards ablation with a focused intense laser beam. The outstanding new feature of micro glass processing is its ability to drill fine channels unlimited apsect ratio and create hollow cavities in glass, and to cut or to mill glass.

Pico Second LASER EdgeWave's ultra short pulse lasers are diode-pumped and mode locked solid-state oscillators and amplifiers.
The amplifiers are based on the unique INNOSLAB laser technology.
Through an optimal combination of crystal shape, cooling and resonator design, ultra short pulse lasers with INNOSLAB amplifiers poss special qualities:
- Compact setup
- High efficiency and high amplification factor
- High beam quality
- Scalability for multi kW
Nano Second LASER EdgeWave's short pulse lasers are diode-pumped and q-switched solid-state lasers, based on the unique INNOSLAB laser technology.
Our standard short pulse laser product encompasses electro-optical Q-switched INNOSLAB lasers with various laser medium, pulse energy and output power and a choice of wavelengths:
A distinguished and enabling feature of INNOSLAB lasers is the tailored beam profile: from circular Gaussian, through line shaped one dimensional Top-hat to square two dimensional Top-hat.
INNOSLAB LASER
In a q-switched INNOSLAB laser a slab shaped and contact cooled crystal and a Pockel cell are used.
A typical intensity distribution of the output beam in near field is shown in the following figure on the left. Along the small dimension of the pumping cross section the intensity distribution is Gaussian and along the large dimension the intensity profile is nearly top-hat with slight diffraction structures.
By using a cylindrical telescope and a spatial filter the laser beam cross section can be symmetrized. The figure on the right shows a typical intensity distribution in far field. After the spatial filter, a rotational-symmetric beam is produced with a beam quality M2 in one direction of 1.1 and of 1.2 in the perpendicular direction.
Using a special beam shaping optic the original one dimensional top-hat beam can be transformed to a two dimensional top-hat beam with a rectangular or a square cross section. Laser beams with two dimensional top-hat and rectangular or square cross section are ideal beams for ablation processes with high throughput.
A distinguished and enabling feature of INNOSLAB lasers is the tailored beam profile: from circular Gaussian, through line shaped one dimensional Top-hat to square two dimensional Top-hat – customizable for your requirements.
INNOSLAB Amplifier
In the INNOSLAB amplifiers high gain, high efficiencies and high damage threshold are unified by matching the beam cross section to the peak power of the amplified laser radiation after each pass via beam expansion defined by the cavity-like folding mirrors. This enables high amplification factor of the laser power or pulse energy at high efficiency and high beam quality.
In order to scale power and energy output oscillator-systems (MOPA) are often used. The main problem in most MOPA designs is to obtain efficient amplification with a large amplification factor due. The problem is due to the controversial behavior between the saturation for high efficiency and the gain for a large amplification factor. This problem is solved by the INNOSLAB amplifier design where a slab shaped crystal and two folding mirrors for generation of multipass are used. The slab crystal is pumped by diode lasers.
Based on the INNOSLAB amplifier design discussed above large amplification factor and at the same time obtaining
