Thorlabs Laser Diodes, Unbiased LASER DIODE SELECTION GUIDE, Compare all Manufacturers and Product Data Sheets on One Site, 370nm to 2350nm. Now compare the maximum power density to that which is specified as the LIDT for the optic. 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. The L405P150 from Thorlabs Inc is a Laser Diode with Wavelength 405 nm, Output Power 0.15 W, Operating Voltage 4.9 to 5.5 V, Operating Current 0.138 to 0.17 A, Output Power (CW) 0.15 W. More details for L405P150 can be seen below. Do not clean the fiber connector when the diode is in operation. When an optic is damaged by a continuous wave (CW) laser, it is usually due to the melting of the surface as a result of absorbing the laser's energy or damage to the optical coating (antireflection) [1]. For short pulses, energy density becomes a constant with spot size. The maximum ratings mean the limitation over which the laser should not be operated even instant time. The mounted aspheres are readily adapted to our SM1 series of lens tubes by using our Aspheric Lens Adapters. The optional 405 nm laser output is delivered on its own single mode fiber and is combined after the beam expander in the Scan Head module. Therefore, as the light diverges, an elliptical beam will result. The L405G2 from Thorlabs is a 405 nm, 35 mW laser diode suited for a variety of applications, such as fluorescence and spectroscopic measurements, flow cytometry, imaging and microscopy, and materials processing. Remember, for optimum coupling the spot size of the focused beam must be less than the MFD of the single mode fiber. Thorlabs offers a large selection of mounted and unmounted aspheric lenses to choose from. For our selection of IR molded aspheres, click here. Safe Practices and Light Safety Accessories. Contact Tech Support for more information. The clear aperture of the unmounted lens is different on either side. Links to the files can be found by clicking on the item number in the price tables below. If you wish to convert your elliptical beam into a round one, we suggest using an Anamorphic Prism Pair, which magnifies one axis of your beam. Additionally, for highly transparent materials, there is little to no drop in the LIDT with increasing PRF. To collimate light using one of our mounted aspheric lenses, orient the housing so that the externally threaded end of the mount faces the source. 405nm Blue Laser Diode Definition : The most common blue laser is a 405nm semiconductor diode laser. Unfortunately, it can be very difficult to compare the LIDT specification of an optic to your laser. These 1/2 (12.7 mm) and 1 (25.4 mm) cubes have a dielectric V-coating on four faces that minimizes re Assuming a divergence angle of 30° (FWHM) and desired beam diameter of 3 mm: Note that the focal length is generally not equal to the needed distance between the light source and the lens. Thorlabs specializes in the building blocks for laser and fiber optic systems. In this regime, the LIDT given as an energy density can be applied to any beam diameter; one does not need to compute an adjusted LIDT to adjust for changes in spot size. 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. For long pulses to CW, linear power density becomes a constant with spot size. A simple example will illustrate the key specifications to consider when choosing the correct lens for a given application.
