摘要： In a disclosed laser module, a usage amount of organic adhesive is set to no more than 1.0 g/ml. Thus, an equilibrium density of outgas components from the adhesive after an air removal treatment is less than 1000 ppm. In another laser module, a heat sink at which a semiconductor laser element is adhered on a submount, an electrode terminal wire-connected with the laser element, a photodiode wire-connected with the electrode terminal, and a zeolite adsorbent are fixedly provided on a stem. These are ring-welded in a container in a dry air atmosphere (80% nitrogen, 20% oxygen). In still another laser module, sixteen multiplexed lasers are disposed in a container. The container is connected with an air circulation apparatus, which is provided with a filter for removing contaminants, a rotary pump for circulating inert gas, and a valve for controlling replenishment of the gas.

摘要： A laser module includes a semiconductor laser that emits laser light within a wavelength range of 350 to 450 nm, and hermetically sealing members, in which the semiconductor is sealed. The amount of organic adhesive utilized within the volume of the sealed sealing members is 1.0 g/ml or less, thereby causing a saturation concentration of outgas components generated from the adhesive to be less than 1000 ppm following a deaerating process. At least one optical component (e.g., a collimating lens) is adhesively fixed to a fixing member (e.g., a collimating lens holder) by inserting an adhesive composition including an alicyclic epoxy compound, a compound having an oxytanyl group, and a catalytic amount of an onium salt photoreaction initiator therebetween at an adhesive thickness of 0.05 μm or greater and 5 μm or less. Thereafter, the adhesive composition is cured by an activated energy beam to fix the optical component to the fixing member.
