The fiber is very fragile and easily broken. These specifications are achieved through a patented design consisting of a single angled facet (SAF) gain chip coupled to a fiber Bragg grating (FBG) enclosed in a hermetically sealed case.1 Two integrated thermoelectric coolers (TECs) and thermistor pairs act in a closed loop to control the temperature of the gain chip and FBG independently. This class of laser is safe under all conditions of normal use, including use with optical instruments for intrabeam viewing.

The maximum instantaneous optical power output by the laser. Customers that require a specific wavelength may contact tech support to place a special order. 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 800 mA. Edge-emitting laser diodes also emit astigmatic beams, and it can be desirable to force the displaced focal points of the orthogonal beam components to overlap. Laser emission in the visible and near infrared spectral ranges has the greatest potential for retinal injury, as the cornea and lens are transparent to those wavelengths, and the lens can focus the laser energy onto the retina. www.thorlabs.com Specifications subject to change without notice. The amount of time between the start of one pulse and the start of the next. Contact me for details. However, each type of laser uses a different grating feedback configuration, which influences performance characteristics such as output power, tuning range, and side mode suppression ratio (SMSR). 2. 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. Thorlabs offers packs of fifty 2-56 screws (SH2S019) as well as a 2-56 tap (TAP256) to aid in installation. In this configuration, it is not possible to independently adjust the temperature setpoints of the ULN gain chip and fiber Bragg grating (FBG) without reducing the mode-hop-free range. The ECM225 and ECM175 are two of Thorlabs' family of aluminum side clamps that are designed to securely mount Thorlabs' rectangular electronics housings. The red icon next to the serial number then allows you to download L-I and spectral measurements for that serial-numbered device. Users requiring the maximum possible mode-hop-free tuning and/or current range should select the current-tuning configuration, while users wishing to thermally tune the output wavelength without impacting the output power should select the temperature-tuning configuration. In addition to these, we offer related items, such as receivers and customized catalog products. The grating period can be changed by introducing thermal stress to the fiber, allowing users to temperature tune the laser output while being able to independently stabilize the gain medium's temperature. The DFB laser is the most stable single-frequency, tunable laser configuration. 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. Product Specifications View similar products. Operate a laser at the minimum power necessary for any operation. It is critical to monitor the laser's environment to limit external noise contributions like acoustic and seismic vibrations, as well as driving the laser with a low-noise current source. Customization options include internal laser sources, operating wavelength ranges, optical fiber types, and amplifier types. The component of the beam corresponding to the narrower dimension of the aperture has a greater divergence angle than the orthogonal beam component. However, because the FBG temperature influences the supported lasing modes, the single mode regions shift. We would like to use the NPL41B with a wave guide. All beams should be terminated at the edge of the table, and laboratory doors should be closed whenever a laser is in use. Laser line mirrors are fabricated with specialized coatings that offer high damage thresholds, making them well suited for use with a range of high-powered CW or pulsed laser sources. Do you have a wave guide that I can use? Because of the blink reflex, this class of laser is classified as safe as long as the beam is not viewed through optical instruments. The single-electrode DBR laser provides similar linewidth and tuning range as the DFB (<5 nm). Both Clamps Compatible with all NPL Series Laser Housings, ECM225 Attaches to Bottom or Top of Laser Housing, ECM175 Attaches to Sides of Laser Housing, Compatible with Our Nanosecond Pulsed Laser Systems.

Thorlabs specializes in the building blocks for laser and fiber optic systems. These compact … The ECM225 has three #8 (M4) counterbored through holes, and the ECM175 has one. 1. 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. 4. 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. Do not clean the fiber connector when the diode is in operation.

I could not find an appropriate one on your site. 370nm to 532nm. Important Notes: 1. Ultra-Low-Noise Hybrid LaserThorlabs Ultra-Low-Noise (ULN) Hybrid Lasers each consist of a single angled facet (SAF) gain chip coupled to an exceptionally long fiber Bragg grating (FBG). (I am primarily interested in the 405nm device, i.e. Can you make one of these pulsed lasers at 1035 nm (or 1030 would be close enough). Laser emission in the visible and near infrared spectral ranges has the greatest potential for retinal injury, as the cornea and lens are transparent to those wavelengths, and the lens can focus the laser energy onto the retina. 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.
