01.09.11: Pulsed Power beyond 3 Watts

eagleyard‘s newly introduced 808nm TEM00 High Power Laser Diode has now proven its superior performance also in pulsed mode operation. Excellent inductance values have been achieved through optimizing the wiring scheme. Thus resulting in 2 nsec short pulses at repetition rates of 0.5 MHz. The optical peak power is exceeding 3W giving our customers a powerful tool on hand to solve their design challenges.

23.05.11: TEM00 goes 800 mW

eagleyard’s latest product innovation comes with the release of a new high power, single mode, Fabry Perot laser diode with a center wavelength of 808nm and a typical spectral linewidth of around 1nm. With an emitter facet width of just 4µm, the new laser diode emits 800mW of optical power in a TEM00 beam, thus enabling both high power and high brilliance from a single semiconductor laser. The new laser diode has already completed lifetime performance tests under accelerated conditions (1000mW) and over 750 hours with excellent results. A 1W configuration (also single mode) has additionally completed testing by one of eagleyard’s lead customers. The laser diode is available as standard on a C-mount heat sink, all product specifications have been finalised and engineering samples can be ordered immediately. A fiber-pigtailed version is planned for later in 2011, with additional wavelength (e.g. 830nm) to follow. The optical performance provided by the new laser diode makes it ideal for laser scanning and other optical measurement applications, in particular where an optimum beam quality at high power is critical

19.05.11: Robust pulsed power

eagleyard’s new range of high-power semiconductor laser diodes have been designed for a variety of applications requiring a flexible and environmentally-robust pulsed source. The pulse length can be varied between 200ns and 5µs, with duty cycles ranging from 0.1 to 50% and with output power being offered from 8 to 60W, depending on customer needs. Operating wavelengths are currently 808 and 905nm, although alternative wavelengths are already being planned.

According to Michael Kneier, VP Sales and Marketing at eagleyard, “These new laser products have already been extensively tested and qualified by one of our most demanding key customers, so we can be entirely confident of their suitability for demanding applications.”

Kneier emphasizes that these new lasers were especially developed to meet the select performance specifications of the customer. “The ability to use these lasers in extreme conditions represents one of the principal selling points. For example, a specified temperature range from -45 to +90°C and the passing of a set of extreme mechanical stress tests delivers a product designed for the needs of very demanding applications.”

11.10.10: Our butterfly packaged DFB diodes are now qualified for GAIA's deep space mission

Please watch eagleyard's contribution to the ICSO Conference organized by ESA and CNES, which was held 4-8 October 2010 in Rhodes, Greece. Sascha Tornow reported on

"QUALIFICATION OF AN EVALUATED BUTTERFLY-PACKAGED DFB LASER DESIGNED FOR SPACE APPLICATIONS"

An extended qualification program has proven the quality of a previously evaluated semiconductor laser diode, which is intended to be used in a subsystem for the GAIA mission. We report on results of several reliability tests performed in subgroups. The requirements of the procurement specification with respect to reliability and desired manufacturing processes were confirmed.

26.01.09: eagleyard contributes to OPTO - Part of SPIE Photonics West 2009

Please watch eagleyard's contribution to the SPIE OPTO Conference which was held 24-29 January 2009 in San Jose, United States. Dr. Joerg Wiedmann will discuss a "Green light source by single-pass second harmonic generation with laser and crystal in a tilted butt joint setup."

Conference: #7212
Paper Number: #7212-10

In this work a compact green laser light source is presented based on a single-pass second harmonic generation (SHG) in non-linear material. The green light source consists of a distributed feedback (DFB) laser with a monolithically integrated power amplifier (PA) and a periodically poled lithium niobate (PPLN) crystal with a ridge waveguide. To achieve the smallest size and to reduce the number of parts to be assembled, a direct coupling approach is implemented without using any lens.
