Request InfoDakota Technologies Inc.The Northern Lights tunable dye laser from Dakota Technologies Inc. features a Bethune prism dye cell inside the oscillator-only Littman grazing incidence cavity. Because the pump beam is delivered collimated to the pump cell, pump-beam alignment takes seconds. The laser provides 5 to 10 mJ between 546 and 800 nm and up to 1 mJ in the UV after frequency-doubling. The compact laser measures 12 x 2.5 x 4.5 in., offers mechanical repeatability of <0.01 nm and is available in computer-controlled and manually tuned models. The circularly symmetric output beam has a bandwidth of less than 0.5...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra January 2023 IssueInGaAs Quad and Array PhotodiodesInGaAs quadrant and array photodiodes from Marktech Optoelectronics Inc. are designed for laser alignment and position sensing applications.
