Nd:YAG lasers
The Y70S series of OEM, industrial, diode-pumped Nd:YAG lasers uses a longer cavity to produce a stretched pulsewidth and lower-peak power for high-precision materials-processing applications. It delivers >6.5 W at 1064 nm with repetition rates up to 100 kHz, with M2<1.2. In harmonic generation, it has an average power of >3 W at 532 nm. The modular design with self-aligning connectors allows in-field replacement as well as automated control of the doubling harmonic module.

Turning mirrors
A line of laser turning mirrors and reflectors can be used in dirty industrial environments with carbon-dioxide lasers emitting at 10.6 µm. Available are molybdenum mirrors that have >98% average reflectance at a 45° angle of incidence and that can withstand frequent cleaning due to their intrinsic hardness. Silicon turning mirrors come with enhanced silver or DBMR dual-band coatings with 99.5% and 99.7% average reflectance. Silicon and copper phase retardation reflectors have <1.5% absorption.

Miniature convergent-mode sensors
The new VS2 Series Convergent-Mode Sensors are self-contained miniature sensors (measuring 25.1 x 12.0 x 3.6 mm) allowing access to confined areas previously accessible only to fiberoptic or remote-sensing devices. The sensors utilize a visible red sensing-beam to provide a 15- or 30-mm range, depending on model, and repeatability of 160 µs with an output response time of 1 ms. Applications include small machinery, microelectronic handling equipment, vibratory feeders, and punch presses.

Optical layout software
OLIVE (Optical Layout Including Video Elements) is a newly introduced optical layout software package that simulates the optical bench on any computer running Windows 95/98/00 or NT. Users may grab, add, or move the lenses with the mouse, and OLIVE traces the rays in real time. Features include the calculation of chromatic and seidel aberrations, identification of limiting apertures and field stops, and the ability to customize and save lens designs. OLIVE designs may be exported to Zemax or Code V formats for optimization.
