laser for interferometry and holography
Toptica has released its Bluemode laser, suitable for interferometry and holography. It unites high power, high coherence and superior mode stability in a compact and rugged design. The Bluemode lasers deliver 50mW at 405nm, 20mW at 445nm and up to 30mW at 488nm and provide a coherence length greater than 25m. OEm solutions are provided upon request. The Bluemode laser provides
high powers in single-frequency operation. all versions feature a spectral line width below 5mHz, a wavelength stability of ‹0.05pm/h and long-term power stability better than 0.5 per cent (STD/mean, in constant environmental conditions). Combined with excellent long- term coherence stability, this renders the laser a perfect fit for applications requiring low intensity and frequency noise, and continuous single-mode operation. The output beam diameter is approximately 1mm, close to that of conventional ion lasers, making the transition to a Bluemode laser a smooth process.

Diode laser bars at 1,210 and 1,320nm
Dilas has broadened its range of diode laser bars with the addition of two new wavelengths at 1,210 and 1,320nm, which offer wall- plug efficiencies of greater than 40 per cent. The two new laser bars mean that Dilas now offers specific wavelengths in the 1-2µm range of 1,064, 1,210, 1,320, 1,470, 1,550 and 1,940nm. Based on conduction-cooled
diode laser arrays, Dilas’ fibre- coupled diode laser modules generate output powers of 12, 25, 40, or 100W, using a standard single core 600µm fibre with a numerical aperture of ‹0.22 and Sma-905 fibre connector. Such fibre- coupled diode laser modules are
300mW cW laser diode module
Roithner Lasertechnik has introduced a low-price, high- power ULV-445-300 laser diode module with 300mW CW of optical power. The module emits a 445nm blue collimated laser beam. The compact laser head (30 x 30 x 62mm) allows for seamless system integration and silent operation. although passively cooled, a long time (4 hours) stability of ‹5

ES Technology (Kingston, UK) has added a new selection of frame styles and materials to the range of Univet laser safety eyewear it distributes in the UK. The eyewear products manufactured by Univet (Brescia, Italy) cover both laser and IPL (intense pulsed light) applications. Users can select a product that not only provides high protection levels, but also offers long lasting comfort and style.

Laser Components has added Firecomms’ OptoLock optical transceivers to its range. The IDL301T-220 uses a plastic optical fibre (POF) and offers hardened immunity to EMI/ EMC interference, as well as excellent ESD performance. Using an eye-safe resonant cavity light emitting diode and hybrid Si photodiode receiver, Ø1.5mm or Ø2.2mm white or black POF can be cut with a simple knife and pushed into the receptacles. It provides a 650nm 125Mb/s fibre optic transceiver fully IEEE 802.3u compliant for full control over 100Mb Ethernet.
