Laser Optics

Alpine Research Optics (Boulder, CO) has released a Spectral Shaping Filter providing a route to shorter pulses from titanium:sapphire amplifiers. This intra-cavity optic is a dielectric coated filter with a spectral transmission curve designed to compensate for spectral narrowing due to gain flattening. The optic is available in 1" and 2" diameters. Both the center wavelength and the magnitude of the single-pass gain correction can be adjusted with the filter. Varying the angle of incidence at which the optic is mounted causes a shift in the center wavelength. This enables the filter’s performance to be matched to the skewed spectral gain curve of chirped amplifiers. By rotating the filter angle relative to the beam polarization, its transmission maximum can be increased or decreased, allowing the same filter to be used in both a multi-pass or regenerative-type amplifier.

Scanning Probe Microscope

The Caliber™ scanning probe microscope (SPM) from Veeco Instruments (Woodbury, NY) can perform various SPM research and industrial applications on samples of differing sizes. The SPM’s open-platform, closed-loop design allows researchers to customize hardware. Features include real-time software with line-by line analysis, oscilloscope, FFT, and leveling functions. Proprietary electronic control provides a triple-DAC design for 16-bit scan control at any scan range and offset. The system utilizes integrated optics with a color camera, enabling engineers to judge tip-sample separation. Image modes include contact mode, tapping mode, phase imaging, lateral force microscopy (LFM), force modulation microscopy (FMM), force distance curves, and optional nanolithography. The system can scan up to 90μm on most surfaces.
