LASER 2009: new product focus
Products and announcements from KLASTECH, Photonics Industries and 3S Photonics.
CW ruby laser
KLASTECH, Germany, will be exhibiting what it claims is the industry’s first CW diode-pumped solid-state (DPSS) ruby laser. Dubbed the CRESCENDO, the laser utilizes the company’s proprietary approach for pumping the ruby crystal and the same DENICAFC “double-enhanced laser technology” common to other lasers in the KLASTECH range. “This laser for the first time not only provides a ruby-based CW source, but also offers the first single-frequency, ultralow-noise DPSS laser in the visible red region of the spectrum, opening up new possibilities to researchers in biophysics and DNA sequencing,” says KLASTECH. The CRESCENDO is available initially in 100 mW and 150 mW versions, with plans to increase its power output to 500 mW in the near future.

Diode-pumped picosecond lasers
Photonics Industries (Bohemia, NY) says that its RG Series diode-pumped picosecond lasers produce over 3 mJ per pulse at 1 kHz, and more than 10 W at 10 kHz at 1064 nm with ~15 ps nominal pulse widths - all while still maintaining TEM00 mode quality in a compact, industrial-grade package. Higher-power versions (25 W and 40 W at 10 kHz) or higher-pulse-energy formats (5 mJ/pulse and 7 mJ/pulse at 1 kHz) are also available. Harmonic outputs such as 532 nm, 355 nm, 266 nm and 213 nm can be ordered as needed. According to the vendor, “high-pulse-energy picosecond laser pulses with good beam quality can competitively machine thicker materials or materials with feature sizes of ~1 mm. Such mesoscale laser processing with less heat-affected zone is proving in for a myriad of novel applications on materials such as metals and ceramics.”

1064 nm pump module
3S Photonics, France, will use LASER 2009 to unveil its first product for non-telecoms applications. The 1064 nm singlemode pump-laser module, the 1064 CHP, is designed for integration into industrial fibre-laser systems used in micromachining applications. Features include output power up to 400 mW at 850 mA and peak power up to 1W; a low-profile hermetically sealed 14-pin butterfly package with polarization-maintaining fibre pigtail; integrated thermoelectric cooler, thermistor and back-facet monitor photodiode; operating temperature range from -5 to +75 °C; and operating wavelength range from 1050-1070 nm. Users can choose from two options: a fibre Bragg grating version for wavelength stabilization and a “High PER” format with polarization extinction ratio exceeding 20 dB.
