A laser arrangement comprises an optically pumped laser (2) and at least one semiconductor laser (1) which emits pump radiation (6) for pumping the optically pumped laser (2). The semiconductor laser (1) contains a plurality of monolithically integrated active zones (3, 4, 5) arranged one above another, at least two of the plurality of active zones (3, 4, 5) emitting pump radiation (6) of different wavelengths. In this way, it is possible to pump different absorption bands of the optically pumped laser (2) using a single semiconductor laser (1).
摘要:
An edge emitting semiconductor laser containing a plurality of monolithically integrated laser diodes (1, 2, 3). Each laser diode (1, 2, 3) contains an active zone (11, 12, 13), with the active zones (11, 12, 13) being in each case arranged between waveguide layers (6), the waveguide layers (6) in each case adjoining a cladding layer (7, 8) at a side remote from the active zone (11, 12, 13). The cladding layers (7, 8) comprise inner cladding layers (7), which are arranged above a bottommost active zone (11) and below a topmost active zone (13), and outer cladding layers (8) which are arranged below the bottommost active zone (11) or above the topmost active zone (13). The inner cladding layers (7) have a smaller thickness than the outer cladding layers (8).

摘要:
The invention relates to a method and device for the continuous polycondensation of polyester material in the solid phase, in particular in the form of partially crystalline granulate. The aim of the invention is to achieve a high product throughput on recrystallising and recondensation of polyester material with a low initial IV. Said aim is achieved, whereby on recrystallisation, a low residence time of 1-10 minutes is achieved, by means of a rapid heating of a thin product layer, followed by an SSP treatment.
摘要:
A real-time system for modeling a turbo-charged engine includes a model configured to estimate various exhaust states such as turbine inlet pressure, turbine outlet pressure, turbine outlet temperature, turbine mass flow rate and waste-gate valve mass flow rate. The model is dependent only on the availability of normal operating values available in a conventionally-configured automotive controller and one or more measured intake side parameters such as ambient pressure, boost pressure, ambient temperature and compressor mass flow rate. The model is constructed to reflect a high-level application of energy conservation between the turbine (generated power) and compressor (absorbed power). A method for the indirect measurement of turbine and waste-gate flow uses turbine inlet and outlet pressure, inlet temperature and engine mass air flow rate measurements. A method for the indirect measurement of turbine efficiency avoids the need for manufacturer's turbine data.
