Temperature Control Range of the LDM-4409

The LDM-4409 brochure states that a 25W heat load can be controlled over a temperature range of 10ºC to 85ºC, but this is only for short term experiments such as LIV testing. This technical note will look at longer term temperature control of the LDM-4409.The LDM-4409 is a temperature controlled mounting fixture designed for C-Mount (Block) laser diodes with current input up to 10A. A 7.4A, 14.6V TE module is used behind the cold plate; the heat is then removed via a large finned heat sink and built-in 5V fan.
