Are the lasers lateral or longitudinal multi-mode when you state in the spec. Proper ESD Protection should be worn whenever handling a laser diode. Thorlabs specializes in the building blocks for laser and fiber optic systems. Assuming that the width of the lens is negligible compared to the radius of curvature, the thin lens approximation can be used to determine the appropriate focal length for the asphere. Because there is a maximum current which cannot be exceeded even for a very limited amount of time, spikes in electronics will cause immediate damage. The red icon next to the serial number then allows you to download L-I-V and spectral measurements for that serial-numbered device. Your help is highly appreciated. All class 2 lasers (and higher) must display, in addition to the corresponding sign above, this triangular warning sign. We had to pass your inquiry to our technical support staff in Japan, who then in turn had to contact the vendor. According to the vendor, the wavelength variation/current variation is about 0.04 nm/mA and the wavelength variation/temerature variation is about 0.2 nm/K. Dear All, Is it also this diode laser provided by scanning head to mark barcode code? A response from Laurie at Thorlabs to mph: Thank you for your feedback on our website. Laser diodes with a built-in photodiode can operate at constant power. Figure 4: The diameter of a Gaussian beam is often given in terms of the 1/e2 full width. I will contact you directly to discuss your application. Regards It has an integrated optical isolator, thermoelectric cooler (TEC), thermistor, and a photodiode. View the full list of new products (below) or browse our entire product range.All of these items are available now!Choose RSS Feed to have this information delivered to you. Because of the blink reflex, this class of laser is classified as safe as long as the beam is not viewed through optical instruments. Safe practices and proper usage of safety equipment should be taken into consideration when operating lasers. Thank you very much, I will work on getting the price of the diode fixed right away. Rodolfo. A socket is included to assist with soldering. Kolkata Branch Laser Diodes by Wavelength Laser diodes, which are capable of converting electrical current into light, are available from Thorlabs with center wavelengths in the 375 - 2000 nm range and output powers from 1.5 mW up to 3 W. We also offer Quantum Cascade Lasers (QCLs) with center wavelengths ranging from 4.05 to 11.00 µm. The DBR816PN from Thorlabs is a Distributed Bragg Reflector (DBR) Laser Diode that operates at 816 nm. In some cases, these plots will be limited to the spectral resolution of the spectrometer used. While the connectors on the pigtailed laser diodes are cleaned and capped before shipping, we cannot guarantee that they will remain free of contamination after they are removed from the package. Figure 2: The blade traces an arc length of Rθ through the center of the beam and has a angular rotation rate of f. The chopper wheel shown is MC1F2. Visible, continuous-wave lasers are limited to 5 mW of output power in this class. Heat Sinks:Laser diode lifetime is inversely proportional to operating temperature. Also do Thorlabs offer AR coated LD? Response from Jeremy at Thorlabs: We do not have any data on using this laser diode in an external cavity. A point on the blade located a distance R  from the center of the wheel sweeps through an arc length (Rθ ) that is approximately equal to the size of the beam along this direction. Thanks. When operated within their specifications, laser diodes have extremely long lifetimes. The arc length (Rθ = R ⋅ ftr ) through the beam can be calculated using this angle. Members of our Tech Support staff are available to help you select a laser diode and to discuss possible operation issues. This web page contains Thorlabs' laser diodes with center wavelengths from 705 nm to 2000 nm. Hello, thank you for contacting Thorlabs. Thank you! Thorlabs' Laser Diode Modules are available in either collimated or adjustable-focus varieties and provide output powers ranging from 0.85 mW to 4.5 mW (laser safety Class 2, 3R, or 3B depending on the model). A fiber-pigtailed laser should always be turned off before connecting it to or disconnecting it from another fiber, especially when the laser is at power levels above 10 mW.
