Optomechanics, optics, opto-electronics, laser … Consider the laser's performance when driven with currents between 700 and 725 mA. In general a DBR can incorporate various regions not typically found in a DFB that yield greater control and tuning range. Equal to the reciprocal of the period. Thorlabs' current-tuning ULN laser provides a wide range of currents where the laser operates in a single mode when compared to the temperature-tuning configuration. The laser should be off when plugging or un-plugging the connector. The following sections give an overview of our spectrum of custom and catalog products, from fully integrated instruments to component-level modules. By changing the effective index, the lasing wavelength can be tuned. The clamp must be mounted via the counterbored through hole before the electronics housing is attached, as the counterbore will not be accessible once the housing is secured in the clamp. We recommend the IOT-G-1550A dual-stage isolator, which can achieve a peak isolation of 55 dB; alternatively, two fiber-coupled isolators can be used inline to achieve a similar isolation. In addition, each laser features an auxiliary thermistor that monitors the case temperature and a built-in monitor photodiode. 3. The ULN15PC from Thorlabs Inc is a Laser Diode with Wavelength 1530 to 1565 nm, Output Power 100 to 140 mW, Output Power 100 to 140 mW, Operating Current 650 to 800 mA, Operating Current 650 to … Techniques for circularizing an elliptical beam include those based on a pair of cylindrical lenses, an anamorphic prism pair, or a spatial filter. These laser diodes are made in-house at Thorlabs' semiconductor manufacturing … Do not clean the fiber connector when the diode is in operation. The ECM225 has three #8 (M4) counterbored through holes, and the ECM175 has one. The bandwidths of these lasers are a few nm, so whether they can be used in an interferometric application depends on the coherence length required. ultra-low noise laser. In the image of the experimental setup, all of these systems are shown on the right side of the table for illustrative purposes; they were used one at a time. For instance, a multiple-electrode DBR laser can include a phase-controlled region that allows the user to independently tune the phase apart from the grating period and laser diode current. Click to Enlarge Figure 1: ECL Lasers have a Grating Outside of the Gain Chip. Thorlabs Inc. Do not clean the fiber connector when the diode is in operation. The frequency with which pulses are emitted. However, diffuse reflections are not harmful. Hello, thank you for contacting Thorlabs. I. In contrast to the complicated control structure for the multiple-electrode DBR, a simplified version of the DBR is engineered with just one electrode. These laser systems include the laser head, a +15 V power supply, a 2 mm flathead screwdriver, and two ECM225 clamps for post mounting the laser head. This webpage contains Thorlabs' pigtailed laser diodes with multimode (MM) fiber. External Cavity LaserThe External Cavity Laser (ECL) is a versatile configuration that is compatible with most standard free space diode lasers. For fiber-coupled optical output options, we recommend choosing from our selection of coupling packages to accommodate the NPL series' larger beam diameter. Thorlabs' offering of laser … To protect the laser diode from damage due to static electricity (ESD), please follow proper ESD handling precautions. Provenance : Italie. Thorlabs offers a range of laser safety accessories that can be used to reduce the risk of accidents or injuries. Edge-emitting laser diodes emit elliptical beams as a consequence of the rectangular cross sections of their emission apertures. Pulse widths are adjustable from 5 to 39 ns over 16 discrete settings with approximately equal spacing. Center Wavelength Options from 405 nm to 640 nm, Compact Laser System with Collimated Free Space Output, Typical Center Wavelength: 405 nm, 450 nm, 488 nm, 520 nm, or 640 nm, Drive and Temperature Stabilization Electronics Integrated into Laser Head, Fixed and Adjustable Pulse Width Models (See Table to the Right), Models with Internal Triggering up to 10 MHz (Item #s Ending in B), High-Power Models up to 1600 mW Peak Pulse Power (Item #s Ending in C), Two ECM225 Clamps Included for Post Mounting the Laser Head, The pulse widths of the lasers with Item #s ending in B or C are adjustable over 16 discrete settings, from the minimum to the maximum specified widths. 1 available. A lens collimates the output of the diode, which is then incident upon a grating (see Figure 1). Our light sources are conveniently separated into coherent and incoherent sources. This 640 nm wavelength pulsed laser system outputs fixed-duration 10 ns pulses in response to a user-supplied trigger input sent to the Trigger In port on the back panel of the laser head (shown to the right). The control for adjusting the pulse width is located on the back panel, which is shown in the image to the right. The laser intensity at the center of the fiber tip can be very high and may burn the tip of the fiber if contaminants are present. VIEW ALL Wavelengths 370nm-532nm » View by Popular Wavelengths. The maximum peak pulse optical output powers vary from 13 mW to 1600 mW, depending on Item #, as specified in the table to the right. Lasers in this class are considered safe as long as they are handled with restricted beam viewing. Avoid handling the fiber by the rubber “boots” of the black housing and connector ends of the pigtail. Contact me for details.
