1.2. QCL housings and packages

ALPES LASERS QCLs can be delivered in 5 kinds of packages:

Chip-on-Carrier (CoC) A laser chip available on stock is mounted on either a NS or

ST submount (see section 1.1.3) . These submounts can be integrated into a

LLH or HHL housing, or can be sold as an such, to be integrated in a piece of

equipment manufactured by the customer.

Laboratory Laser Housing (LLH) The LLH is designed for research applications,

and can be cooled down to -30

◦

C with water cooling. With easy laser exchange

and compatibility with the Starter Kit, it is the most versatile housing available.

All ALPES LASERS available on stock can be used in a LLH housing. See sec-

tion 1.2.1 for details.

High Heat Load (HHL) The HHL housing is a sealed collimated housing with TEC

for CW or pulsed lasers. The optional collimating lens is protected by a plane

window, making it ideal for operation in aggressive environments. See section

1.2.2 for details.

TO3 Pulsed lasers are available in TO3 cans, which are smaller and less power-

intensive than the HHL packages. TO3 housings are sealed, include a TEC and

are available with AR coated lenses for beam collimation or ﬂat windows. Their

small size and low dissipation (less than 4W in pulsed mode) make them ideal

for integrating the QCL in a piece of equipment manufactured by the customer.

Note: most lasers listed on ALPES LASERS website cannot be mounted in a

TO3 housing; address your inquiry directly to ALPES LASERS.
