It maintains a typical stability of 0.0005 °C/°C with respect to room temperature, and … CAB420-15. Temperature Controller. Power supply : 24 V Applications of these high power laser diode include laser pumping, fiber laser development, direct diode micro-machining etc. For more cooling power and even higher temperature stability, the TED4015 225 W temperature controller can be used. 69 (3), 1998. The application of the 635 nm diode laser enhanced secondary implant stability and bone density. One hour temperature stability measurements performed in a typical lab environment, on a Newport laser Mount 764H-110 with an Oclaro BW-series laser running at 10W optical output power. The divergence angles of this cone are measured by the full width-half maximum light power in the axes perpendicular to and parallel to the laser’s active region. �I3��o? Wilson, and M.G. 1310 nm and 1550 nm. The WTCP5V5A PWM Laser Diode Temperature Controller is a compact, powerful and efficient device that delivers all the advantages of Pulse Width Modulated (PWM) control in a compact PCB-mounted package. Threshold currents were calculated at various temperatures and comparable to expected results. This unit features a wide operating temperature range, 12 W of cooling, and high temperature stability. These 100 mm x 160 mm board-level controllers combine a low-noise, low-drift current source with a precise TEC controller. The performance of a diode laser’s temperature control system is closely related to the system’s structure, response and algorithm.
