aluminum base. The stages use a four-point
mounting method, ensuring stability even when
installed on less than ideal surfaces. When
mounted on a proprietary table, the sturdy
stage design ensures accuracy, high throughput
and repeatable, bidirectional performance.
DPSS Laser Amplifier
Microchip lasers with subnanosecond-pulse
duration at 50 kHz and 200-m W output power
have been amplified to > 15 W using the Midaz
Lasers Ltd. Model A50-A diode-pumped solid-
state (DPSS) air-cooled amplifier. The single-
stage amplifier module increases laser output
power and eliminates the cost and complexity
of using multiple preamplification stages. The
combination of seed laser and amplifier can
easily integrate into laser systems for micro-
machining and marking or can be used for
research and development.

Optical Surfaces Ltd. is offering planoconvex
and planoconcave toroidal mirrors for pinpoint
focusing in spectroscopic and imaging applications. The mirrors have two different radii
whose axes are oriented at 90° to each other.
They have advantages in applications where a
beam must be focused and folded. Rather than
requiring both a spherical and a plane mirror
for this purpose, the mirrors combine both functions in one element, enabling increased energy
throughput and more compact designs. Toroidal
mirrors correct for the astigmatism that results
when a spherical mirror is used off-axis. The
company produces custom toroidal mirrors in
materials including Zerodur, BK7 and fused silica, with typical surface accuracy of better than
;/5 (dependent upon size and radius) and
surface quality of 20-10 scratch-dig.

Process Sensors Corp. has added the improved
high-accuracy, low-temperature Metis Model
MB35 sensor series to its line of precision noncontact infrared pyrometers. With an operating
temperature range starting at 35 °C, the pyrometers use a lead selenide detector with filtered
spectral response from 2 to 5 µm. Applications
include CO2 laser heating, composites and
