The new page will go live shortly. A socket is included to assist with soldering. Response from Tim at Thorlabs to Cristina: Thank you for your inquiry. This product is a laser diode current and temperature controller, which can output of to 1A for laser diode current control and 8A for laser diode temperature control. Webpage Features; Clicking this icon opens a window that contains specifications and mechanical drawings. Contact; About Us - powered by LASER LAB SOURCE; search. Visible, continuous-wave lasers are limited to 5 mW of output power in this class. 1) On datasheet of LPM-660-SMA it reads slope efficiency=0,75 mW/mA, output power=22.5 mW and operating current 65 mA. Also, reverse voltages as little as 3 V can damage a laser diode. Can you offer any laser diodes operating on this wavelength. Please see our Laser Diode Tutorial for more information on these topics and laser diodes in general. Hello, I've been trying to modulate an L637P5 with a square wave around threshold. Options are available for sweep rates from 50 kHz to 400 kHz and MZI delays from 8 mm to 72 mm. Can you recommend me a correct fit; please? Each module has an output beam shape that is either elliptical or round, as indicated in the tables below. Safe practices and proper usage of safety equipment should be taken into consideration when operating lasers. Wavelength of your laser; Beam diameter of your beam (1/e 2) Approximate intensity profile of your beam (e.g., Gaussian) Linear power density of your beam (total power divided by 1/e 2 beam diameter) Thorlabs expresses LIDT for CW lasers as a linear power density measured in W/cm. I will contact you directly to determine the exact information that you need. Response from Ken at Thorlabs to BiryukovAA: We do not carry any green laser diodes but we do offer a few green HeNe lasers. Dear All, Dear Thorlabs, could a voltage source drive the LD?Thanks! This laser class also applies to larger-diameter or diverging laser beams. Class 2 lasers, which are limited to 1 mW of visible continuous-wave radiation, are safe because the blink reflex will limit the exposure in the eye to 0.25 seconds. Ross. Thorlabs offers a large selection of aspheric lenses. The L670VH1 is tested to ensure a center wavelength tolerance of ±10 nm. Another thing that can impact the bandwidth measurements is the terminating load resistance being used with your detector/oscilloscope. If optical components are moved within the system and energy is no longer reflected onto the monitor photodiode, a constant power feedback loop will sense the drop in photodiode current and try to compensate by increasing the laser drive current and possibly overdriving the laser. On the other hand, if I want 22 mW output power, from the slope efficiency I calculate 29 mA which is below the threshold current. What is the mode field dia on this LD? Response from Laurie at Thorlabs to dajun.wang: The HL6548FG is AR coated for the wavelength of the diode. All class 2 lasers (and higher) must display, in addition to the corresponding sign above, this triangular warning sign. To collect as much light as possible during the collimation process, consider the larger of these two divergence angles in any calculations (i.e., in this case, use 30°). If possible, reduce the output power of a laser during alignment procedures. This web page contains Thorlabs' laser diodes with center wavelengths from 705 nm to 2000 nm. This system features a 4-wavelength integrated laser source, a 4-channel detection module with stanard sensitivity PMTs. As the rotating chopper wheel's blade passes through the beam, an S-shaped trace is displayed on the oscilloscope. Diodes can be temperature tuned, which will alter the lasing wavelength. Do not use a voltage supply with a current limiting resistor since it does not provide sufficient regulation to protect the laser. Back reflections can also cause other malfunctions or damage to laser diodes. Heat Sinks:Laser diode lifetime is inversely proportional to operating temperature. The monitor photodiode of the DJ532-10 measures the power of the pump source, not the 532 nm output. I will contact you directly to discuss your application. Ø3.8 mm, Ø5.6 mm, Ø9 mm, Ø9.5 mm, and TO-46 Laser Diodes Central Wavelengths Ranging from 375 to 1650 nm Ø3.8 mm Ø9 mm Ø5.6 mm Mounted Laser Diode Laser Diode Mounted Using LTC100-B LD Controller Kit TO-46 Ø9.5 mm Thanks again for taking the time to provide valuable feedback! In addition, laser safety signs lightboxes should be used with lasers that require a safety interlock so that the laser cannot be used without the safety light turning on. Thus almost all laser diodes are temperature tunable, though this tunability is generally small (~10s of nm). These hazards may also apply to indirect or non-specular reflections of the beam, even from apparently matte surfaces. For these diodes, depending on the specific diode, we would recommend using the LDC220C driver. The SL10 series of MEMS-VCSEL Swept-Wavelength Laser Sources, centered at 1060 nm, is available from Thorlabs Inc. with four different sweep rates ranging from 60 to 400 kHz. From optomechanical components to telecom test instrumentation, Thorlabs' extensive manufacturing capabilities allow us to ship high quality, well priced components and devices for next-day delivery. NEWTON, N.J., April 24, 2020 — The ULN15PT line of ultra-low-noise semiconductor lasers from Thorlabs features high output power of >100 mW, a narrow linewidth of <100 Hz, and an ultra-low relative intensity noise of <-165 dB/Hz. Aroop Kanti Bose https://www.thorlabs.com/navigation.cfm?guide_id=2089, Hi there, The tables below list basic specifications to help you narrow down your search quickly. This bandwidth is only applicable to small signal sine wave modulation (not square wave).
