Abstract
In various embodiments, a laser emitter such as a diode bar is cooled during operation via jets of cooling fluid formed by ports in a cooler on which the laser emitter is positioned. The jets strike an impingement surface of the cooler that is thermally coupled to the laser emitter but prevents direct contact between the cooling fluid and the laser emitter itself.
Claims21
A laser package comprising:
- a bottom anode cooler defining at least partially therethrough a plurality of ports for forming jets of cooling fluid therethrough;
- and
- disposed above the bottom anode cooler, a top anode cooler (i) comprising a laser platform for receiving a laser emitter thereon, and (ii) defining a recess therein, the recess (a) being disposed beneath the laser platform and (b) having an impingement surface facing the ports of the bottom anode cooler, whereby cooling fluid introduced into the bottom anode cooler and jetted through the ports strikes the impingement surface of the top anode cooler to cool a laser emitter disposed on the laser platform.
A wavelength beam combining laser system comprising:
- a beam emitter emitting a plurality of discrete beams;
- focusing optics for focusing the plurality of beams onto a dispersive element;
- a dispersive element for receiving and dispersing the received focused beams;
- a partially reflective output coupler positioned to receive the dispersed beams, transmit a portion of the dispersed beams therethrough as a multi-wavelength output beam, and reflect a second portion of the dispersed beams back toward the dispersive element;
- a bottom anode cooler defining at least partially therethrough a plurality of ports for forming jets of cooling fluid therethrough;
- and
- disposed above the bottom anode cooler, a top anode cooler (i) comprising a laser platform for receiving the beam emitter thereon, and (ii) defining a recess therein, the recess (a) being disposed beneath the laser platform and (b) having an impingement surface facing the ports of the bottom anode cooler, whereby cooling fluid introduced into the bottom anode cooler and jetted through the ports strikes the impingement surface of the top anode cooler to cool the beam emitter disposed on the laser platform.
