Laser Line Generator Lenses

Our straight-line generator lenses can be used to display a uniform straight reference line for use in alignment, machine vision systems, construction and process control. In addition, the lenses may also be used on lower power lasers, (note that intensity will be diminished in normal work light and distances). On a 3.5mW laser, for example, the line would be easily visible in normal interior room light at 30 feet. Features

Beam Expander

In its broadest sense, a beam expander is any optical system designed to increase the diameter of a

laser beam. In most cases, the term is taken to mean a telescope designed to take a small-diameter

collimated beam input beam and produce a larger diameter collimated output beam, thus reducing the

divergence of the beam. The beam expander consists of a negative input lens and a positive objective.

The expansion factor is the ratio of the focal length of the two lenses.

TUNABLE TRUE ZERO-ORDER PHASE RETARDATION PLATESTUNABLE TRUE ZERO-ORDER

PHASE RETARDATION PLATES(Patent Pending)

A novel type of phase retardation plates (wave plates) representing a breakthrough in light polarization measurement and control are now commercially available. The UVIR type plate can be adjusted to a quarter or half wave phase retardation for an arbitrary wavelength from 150 nm (vacuum-UV) to 6000 nm (far infrared) and the FIR type from 1 µm to 21 µm .

This is an exclusive feature and has no commercial counterpart. A combination of two optically contacted thin plates cut at a proper angle with respect to the optical axis forms a true zero-order phase retardation plate, similar in design to the Savart plate.

Thus, the new plates replace tens of ordinary phase retardation plates required to cover these ultrawide spectral ranges.

The required phase retardation is achieved by tilting the plates by 8° - 15°. This design is aimed at avoiding light reflection back to the laser system which in many cases results in complications.

Although they have new and exclusive features and have no commercial counterpart, they are offered at very competitive prices, which are typically lower than those of the ordinary plates.

The new phase retardation plates are indispensable in research with widely tunable or broadband laser sources like dye lasers, optical parametric generators and femtosecond lasers.

Applications: polarization measurement and control, laser research, spectroscopy, nonlinear optics, OPO, femtosecond lasers

The alignment for half-wave retardation is achieved when the plate is positioned between two parallel polarizers and by tilting the plate the transmitted light is totally extinguished. In order to rotate the polarisation plane by an arbitrary angle, use the rotation part with degree dialing.

The alignment of a quarter-wave plate is correct when the transmitted light reaches the half of the maximum intensity and it remains constant for an arbitrary rotation of the second polarizer. The retarder design allows generation of both left-hand or right-hand circular polarization. The change of the polarisation state (right-hand/left-hand) is achieved by rotating the plate by 90°.

The alignment procedure is quite simple and after getting some experience the desired polarisation state can be easily adjusted. A major advantage of the novel design is that the retarders are tilted with respect to the laser beam which avoids the back reflection as well as etalon effects. This feature is especially favorable for applications in modelocked lasers.

Alternatively, we supply tuning curves with the dependance of the tilt angle on the wavelength.

Please note that when the plate is not tilted, there is not any definite optical axis as in the case of the ordinary phase retardation plates.

TUNABLE TRUE ZERO ORDER PHASE RETARDATION PLATESTUNABLE TRUE ZERO ORDER PHASE RETARDATION PLATESALIGNMENT PROCEDURE USING THE SPECIAL PLATE HOLDER

1. Orient the holder in such a way that the polarization plane of the incident beam is parallel to either edge of the rectangular plate holder. In the Figure, one possible polarization orientation E is shown; the other one would be the polarization, rotated by 90°.

2. Rotate the screw until the retardation plate is parallel to the plane of the holder. After that align the whole device so that both plate and the holder are perpendicular to the incident beam. The light beam will be then reflected from the waveplate exactly in the backward direction.

3. Rotate the screw, until the requ i red re ta rda t ion i s achieved. The required retardation is achieved by tilting the plate by 8° - 15° (depending on the spectral region) around an axis which is in a plane at 45° with respect to the light polarization (see the Figure).

A modification of our tunable phase retardation plate allows continuous variation of the phase retardation in the range 0° to 360°. The UVIR type plate can be adjusted to an arbitrary phase retardation in the range 150 nm - 6000 nm and the FIR type in the range from 1 µm to 21 µm . The MULTIPHASE plate successfully replaces the expensive Soleil-Babinet and other types of compensators and can be used to analyze the state of light polarization.

The required phase retardation is achieved by tilting the plates 0° - 45° using a special tilt holder. Each plate is provided with tuning curves that allow easy adjustment of the desired phase retardation.

We offer these waveplates at very competitive prices, making them an attractive alternative to other types of phase retardation compensators.

DUAL WAVELENGTH ZERO-ORDER PHASE RETARDATION PLATES DUAL WAVEÒ

for efficient frequency tripling of femtosecond light pulses

Efficient frequency-tripling of laser light requires rotation of the polarization plane of the fundamental F or the second harmonic SH after the frequency doubling crystal in order to make the planes parallel for efficient interaction in the frequency tripling crystal.

The polarization planes are made parallel by using a special dual-wavelength waveplate that introduces a phase retardation equal to l/2 for F (measured in wavelength units), and l for the second harmonic. By rotating the waveplate, the polarization plane of the second harmonic remains unchanged, while that of the fundamental is rotated in order to make the polarization planes parallel for the frequency tripling. The conventional dual-wavelength quartz plates are designed for a single pair of wavelengths F and SH and have very narrow spectral bandwidth due to the multiple-order design.

As a unique and universal solution, ALPHALAS GmbH introduces the Dual-Wave® Tunable True-Zero-Order DUAL-WAVELENGTH Phase Retardation Plate. The differential phase retardation is achievable for an arbitrary pair of wavelengths (fundamental and second harmonic) in an extremely broad wavelength region. Thus, the new dual-wavelength waveplate is extremely universal with respect to the wavelength ranges. Another important advantage is the true-zero order f ea ture t ha t makes these wavep la tes indispensable for use with femtosecond and broadband or tunable laser sources.

The new Dual-Wave® phase retardation plate is a basic component of our femtosecond frequency tripling unit FEST-01 that provides the highest frequency tripling efficiency on the market. The waveplate design is protected by a patent application.

Features: ¨ true zero order at both fundamental and second harmonic¨broad bandwidth (typically 100 nm)¨ phase retardation: l/2 at the fundamental l at the second harmonic ¨ wavelength regions: 150 nm - 6000 nm (type UVIR) 0.8 µm - 21 µm (type FIR)
