1. A method for manufacturing a glass package, said method comprising the steps of: providing a first glass plate, where the first glass plate has a coefficient of thermal expansion, CTE, in a range of about 80-90×10−7° C.−1;providing a second glass plate;providing a frit, where the frit has a CTE that is about 35×10−7° C.−1;depositing the frit onto the first glass plate or the second glass plate;placing the first glass plate on the second glass plate where the frit is located between the first glass plate and the second glass plate;using a laser to direct a laser beam through the first glass plate or the second glass plate towards the frit and then moving the laser beam at a predetermined sealing speed along the frit to heat the frit such that the frit melts and forms a seal which connects the first glass plate to the second glass plate; andwherein the laser beam forms a footprint on the frit, and has a residence time on a given point of the frit within the footprint that is equal to or greater than 100 msec. 2. The method of claim 1, wherein the residence time of the laser beam on the given point of the frit is such that heating and cooling is substantially uniform at both a center and edge of the frit. 3. The method of claim 1, wherein the predetermined sealing speed is about 20-50 mm/s when following a predetermined heating profile to melt the frit and form the seal in a manner that prevents subsequent cracking and delamination of the sealed frit between the first glass plate and the second glass plate. 4. The method of claim 1, wherein the laser beam has a spot size greater than a width of the frit. 5. The method of claim 4, wherein the laser beam has a Gaussian intensity distribution or a substantially uniform intensity distribution. 6. The method of claim 4, wherein the laser beam has a substantially uniform intensity distribution. 7. The method of claim 1, wherein the first glass plate is a soda lime glass plate. 8. The method claim 1, wherein the second glass plate is a soda lime glass plate. 9. The method claim 1, wherein the first glass plate has a strain point of less than about 500° C. 10. The method of claim 1, wherein a strain point of the first glass plate minus an equilibrated temperature of the first glass plate before the sealing is less than about 300° C. for the residence heating time equal or greater than about 100 msec. 11. The method of claim 1, wherein a strain point of the first glass plate minus an equilibrated temperature of the first glass plate before the sealing is less than about 400° C. for the residence heating time equal or greater than about 200 msec. 12. The method of claim 1, wherein a strain point of the first glass plate minus an equilibrated temperature of the first glass plate before the sealing is less than about 500° C. for the residence heating time equal or greater than about 400 msec. 13. The method of claim 1, wherein the sealed first glass plate has residual stress that is not more than about 1500 pounds per square inch. 14. The method of claim 1, further comprising a step of pre-sintering the frit onto the first glass plate or the second glass plate prior to performing the placing step. 15. The method of claim 1, further comprising a step of depositing at least one component onto the second glass plate prior to performing the placing step. 16. The method of claim 1, wherein the laser is used to heat the frit in a manner where a substantially constant temperature is maintained in the frit along a sealing line while the frit melts and forms the seal which connects the first glass plate to the second glass plate. 17. The method of claim 1, wherein the frit includes a vanadium-phosphate glass and a beta-eucryptite filler. 18. The method of claim 1, wherein the frit includes a glass doped with one or more absorbing ions chosen from the group including iron, copper, vanadium, manganese, cobalt, nickel, chromium, or neodymium. 19. A method for manufacturing a glass package, said method comprising the steps of:providing a first glass plate, where the first glass plate has a coefficient of thermal expansion, CTE, in a range of about 80-90×10−7° C.−1;providing a second glass plate, wherein the second glass plate has a CTE that is less than the CTE of the first glass plate;providing a frit, where the frit has a CTE that is about 35×10−7° C.−1;depositing the frit onto the first glass plate or the second glass plate;placing the first glass plate on the second glass plate where the frit is located between the first glass plate and the second glass plate;using a laser to direct a laser beam through the first glass plate or the second glass plate towards the frit and then moving the laser beam at a predetermined sealing speed along the frit to heat the frit such that the frit melts and forms a seal which connects the first glass plate to the second glass plate; andwherein the laser beam forms a footprint on the frit, and has a residence time on a given point of the frit within the footprint that is equal to or greater than 100 msec. 20.
